Tim and his mechanics are honest and knowledgeable. He's saved us a lot of money and hassle. I won't take my Infiniti anywhere else.

Excellent trip, helped us get back on the road during a cross country move. Knowledgeable and friendly.

Was shopping for a new car and stumbled into what appeared to be a great deal. Hadn't set up an appointment the day before as is standard for most shops- just had called that same day I found the car and was at the dealership in a tight spot not wanting to lose the deal. Tim somehow fit me in and they spent 20+ minutes inspecting all over the car. All the while Tim made great small talk and was incredibly friendly. They have a fantastic reputation as technical experts and I can vouch for their business demeanor. Will definitely give them a ring in the event something unfortunate happens with my car.

Tim and his team at Certified Auto Specialist are great! Their integrity is outstanding...too long to discuss details - however, they have saved my husband and I from unnecessary expenses that other auto shops tried to charge us. They are great at what they do and treat their customers with the highest level of respect. We have taken 3 vehicles to them and each time all problems were solved and they did NOT come up with the usual auto shop "and we found x, y, and z that you should also get fixed today". Again, I can't speak highly enough of Tim and his team in regards to their skill, customer service, and prices!!! ~Mary Bost-Owens

Tim and his crew are the best in Edmond. The only place I will ever take my personal and company vehicles. Fast, reasonable, and great customer service.

I truly enjoy taking my vehicles to Tim at Certified Auto Specialists because I know my vehicles will be taken care of properly. He is a stand up guy that can be trusted, one who takes care of his customers! Whether it is an oil change or something more dire, he will take care of you.

Very honest and knowledgeable shop. I won’t take my car anywhere else! It’s hard to find these qualities in an automotive shop now a days.

I live in Moore, and I drive to Edmond to have them work on my car. I have been a customer for several years, and I appreciate that they are honest, reliable, fast at finding the problem and fixing my car. Tim and his team really knows this business. I really feel safe driving my car after they have service it, whether changing the oil or fixing something major. I highly recommend Certified Auto Specialists.

Tim and his team are great! They have always met or beat the big name shops in Edmond! Their honestly and quality of work will keep me coming back with all of my vehicles. I highly recommend them for all your vehicle service needs!

This was the best service I have gotten when something has gone wrong with my vehicle. The service was timely and the cost was well under what was expected. Certified Auto Specialists is 100% recommended. Thank you, Tim.

I took my Antique 2000 Hummer H1 to Certified Auto Specialists for repair of difficult to fix parts and they did a PERFECT Job. The technicians are very professional and the completed repairs work EXCELLENT.

I was referred to CAS by a friend when I needed a new transmission installed in my truck. I called all around town to get prices and Tim had the best price and the referral going for him. Tim and Kyle were both great. They let me choose the day I wanted to bring in my truck so it worked around my work schedule. The best part is they had my truck done by the day they promised it and it runs great. I would highly recommend this shop for your auto repairs. They definitely have a long term customer in me.

Best repair shop in oklahoma. Fair honest and trustworthy. Can't go wrong taking your car to this shop.

Tim has accurately diagnosed every issue with my son's car. He is upfront and honest. We won't go anywhere else.

Very professional. Everything I have had done there has been performed extremely well. I would highly recommend them.

Always excellent service and fair prices! Highly recommend!

ASE certified master mechanic. Above and beyond required level of service. Very thorough diagnostics and repairs. Took their time to get it right the first time. Communication throughout repairs was exceptional. Highly recommended!

Recently, during a warm spell, I had an air conditioning problem with my Grand Marquis LS. Not only was it blowing hot air, but the blower motor was making noises and the fan switch was stuck on high. I took the car by my local Goodyear store and got an estimate that blew me away....and that was just to fix the air conditioning, not the blower motor nor the fan switch. My gut feeling was a cavalier "take it or leave it" attitude from Goodyear. I heard from a friend that he had used Certified Auto Specialist on North Lincoln Blvd. and had been treated very well. I took the car by there and talked to Tim the owner. My first impression was of a knowledgeable and very courteous guy, with a clean shop, work area, and reception area. Tim explained to me very clearly what was causing the cooling problem, and promised to look into the switch and blower motor also. I made an appointment and dropped the car off a couple of days later, telling Tim to take his time, knowing he was busy. Two days later Tim called and said the car was ready to pick up. I had expected, and was prepared to wait a week or so before the repairs could be made. Not only was Certified Auto Specialist fast, but Tim was able to also fix the fan switch and blower motor at the same time, and was WAY UNDER the quote from my local Goodyear Dealer. To say I was pleasantly surprised was an understatement. The air conditioning is now good as new, and at a very reasonable price I could live with. I found Tim and his knowledgeable mechanics to be fast, fair, very competent, and great guys to know. I am very satisfied with the work, and now have a place that I feel will take good care of any further automotive needs I may have. I would highly recommend Tim and his staff at Certified Auto Specialist to any and everyone, especially to women who are often taken advantage of by unscrupulous mechanics and dealerships. Tim, thanks for the cold air....you'll get my business again! Joe Austin-Northwest OKC

I met Tim when they worked on my car one year ago. They are honest, dependable, quick and fair. I will always use them..

A little slow, but good service. I found it a little hard to communicate with the owner, but in the end I understood what he was explaining. I might go back.

I recently moved from Dallas to Edmond and had trouble finding a reasonably priced and honest mechanic specialist to keep my two old vehicles on the road. Over the last 2 years Tim and his staff have resolved numerous issues on my Acura TSX and GMC Sierra. A few weeks ago my Acura power steering pump was going out and Tim went the extra mile to locate a NEW power steering pump that was reasonably priced. They were able to work me in that day and my car was ready that afternoon. I can't promise things will always go that smoothly with how busy they are but I would definitely give them the chance to work on your car. I highly recommend this auto specialist!

Tim and the guy's at Certified have taken great care of me and my vehicle. Which means alot as a single female. I dont know what I would do without them, knowing I have someone I can trust to take care of my car means alot.

Kyle & Tim have taken car of my Scion IQ since I purchased it. They have charged reasonable prices for service & always have quick turnaround time. I have never had to wait more than 30 minutes for my car to be serviced. They have never tried to upcharge, which I greatly appreciate. I have put 50k miles on my little 1.3L engine in the last year & they have kept it running smoothly. I highly recommend them to anyone looking for a solid auto maintenance crew.

Best mechanic in Oklahoma City

I heard about Certified Auto Specialists from a friend. He kept telling me about Tim and how good he was in fixing his cars. I didn't think much of it over the next few months but I needed some work done to my Chrysler 300C. My car was trying to run hot and i thought maybe it was my thermostat but wasn't sure. I decided to let Tim look at it and also my other problem with my front end alignment. Tim diagnosed the problems and fixed it. My car rides really good now and thanks Tim for everything. I will highly recommend sending your car to Certified Auto Specialists and Tim and company will take good care of you and your car.

They rock!

These guys have worked on all three of my vehicles. I have been overly pleased at the customer service and quality they provide. They know who you are and what car you drive by memory. I will not go anywhere else

These guys are amazing. Let's be honest, anytime your car breaks down it's a stressful experience. However, having Tim and Kyle as my family's auto mechanics makes a horrible situation so much easier. I never have to worry about being lied to with these guys. They let you know your options up front and you can tell they're doing their best to look out for their customers' best interest. They're honest, caring and truly make me feel safe when my car is returned to me. Thank you guys for taking care of us and going that extra mile.

I recently brought my 1997 Chevy Z-71 in with some electrical issues after doing some Googling for good mechanics in Edmond as this was my first time needing once since moving here. I landed on Certified Auto Specialists because of the customer reviews, and glad that I did. These reviews are 100% Accurate from my perspective. Certified Auto Specialists were there to consult with me over the phone when I called to see if I could get it in for service. They were very consultative from "hello", and seemed to genuinely care about getting my truck back on the road, and keeping my costs down. We agreed to have them do a diagnostic and they suggested that "they would call me before spending any money". A nice visit, non-salesy conversation, short stay at the shop, as agreeable bill, and a fixed truck is what I got from my experience at Certified Auto Specialist. I think I found my Edmond Mechanic.

I called around to a ton of local places, and this place was not only the cheapest, but I have never had a place be so honest. HIGHLY RECOMMENDED

Excellent, quick, fairly priced work. Very satisfied.

There's no more engine vibration. The replacing of my motor mounts got my eleven year old 1500 Dodge Ram truck performing like a brand new vehicle. These guys are the best in the business.

Tim and his crew have all the new world skills, but old world thinking of knowing how to give the little shop service a lot of us grew up with. I have known Tim the owner over 20 years and will always will do everything he can to satisfy you. Certified Auto Specialist is the only place I will take my vehicles.

These are the master mechanics you are looking for! From routine to specialized maintenance, Tim will not only find a time that will work with your busy schedule, but he will also accomplish the work at a rate that will beat the dealer's price!

Certified Auto Specialists are tops in their field in my opinion. Upon my first visit, I found an extremely helpful guy in Tim the owner. He quickly diagnosed my problem with the car's air conditioning. I needed a part that that was hard to get to, meaning a lot of labor cost. My fan motor was also shot. His quote came in well under the previous quotes I had gotten. I made an appointment to drop off the car, and to my amazement Tim called me two days later saying the car had cold air and was ready to pick up. I was thinking three or four days at the least. I found his service to be great, quick, and efficient . His shop and waiting area were clean, and his help very knowledgeable. I feel like I got great service at a reasonable cost. I would certainly encourage any single women to get a quote from Certified Auto Specialists before going to a dealership and getting ripped off. Tim can do about anything a dealership can do, but faster and more cost effective. It feels great to have a garage that will give you good service and advice, without selling you a bill of goods. I trust Tim and his crew and he'll definitely get my business again. I've got cold air and I'm a happy camper!

You can take what they tell you to be accurate. The prices are very fair. I won't using anyone else. Very pleased with my service here.

Service is always outstanding

I have known Tim the owner for around 20 years, has always been highly professional and honest. I would recomend him and his crew to anyone and he save you alot of money over a dealerships prices.

Tim and his staff at Certified Auto took excellent care of me and my car from the very beginning. From buying my new engine, to picking the right type of suspension, and helping me choose the correct type of battery to replace my old one. I will definitely be taking my baby, my car that is back in for future care when needed. And I would definitely suggest if you want someone to take care of your car, that you can trust, call Tim @ Certified Auto.

This is one shop that I love taking my car to go get work on it's always fast and convient they get the job done and I don't have to worry about them cheating me out of my money. I always get excellent service and would recommend them to anyone!

Tim and his guys provide quick, professional, quality service at a reasonable price. He gives you options, doesn't try to sell you parts or services you do not need, and is a perfectionists at what he does. He genuinely cares about the quality of the service that his shop provides. I highly recommend Certified Auto Specialist.

Tim is the type of mechanic few and far between in this age. He has genuine concern getting your vehicle serviced correctly and honestly. If you're looking for a local independent at a competitive price, the crew at Certified Auto Specialist should suit your needs well.

You can depend on their word and their assessment of your vehicle problems. They will check prices in more than one parts house to get you the best product for your money. Tim and his employees have many years of experience and knowledge of auto mechanics. Considerate and polite in dealings with customers. Will highly recommend Certified Auto Specialist Shop for all your auto needs.

Great product knowledge and great customer service. I would recommend them to all of my friends.

I've been using thes guys for years, and they are the absolute best I've ever been to. Always communicate with me and provide me with multiple options and pricing if and when available. Work is done at a high quality level and always done on time. I refer all my friend and family to this shop when I have the chance. Great location and very reliable.

They are my go-to guys for my car's maintenance. They are courteous, informative, & thorough with the service they provide. I highly recommend them to all of my neighbors.

Tim and Kyle have been maintaining my wife's 2009 Altima and my 2003 Xterra for years. They are both MASTER TECHNICIANS. There is no overselling of maintenance procedures as at the dealerships. You always know the cost. There are no hidden charges. No problem is too big or too small for Certified Auto Specialists to handle. I give them 6 out of 5 stars. That's how good they are.

Hands down the best mechanic in Oklahoma City fast reliable service will not take my cars anywhere else.

Honest, honest. Finally a mechanic I can trust. We will be back with any and all vehicle work.

Very quick and knowledgeable.

I have been coming here for several years to have my car serviced. I appreciate their honesty, swift service , and also they have good prices. They have fixed several things on my car over the years and I feel safe driving my car afterwards. They are very knowledgeable in this field. I highly recommend them.

Tim explained all options throughly, completed service within 24 hours. Felt very confident with his recommendations and service. Would highly recommend scheduling your next needed service with Certified Auto!

Had my wife's care in for an oil change and inspections and all were done timely and with care. I would not hestitate to recommend this company to anyone. Tim is very helpful and explains what they do.

When one of only a handful of Nissan Master Techs in existence opens up his own shop, you know you're in good hands. I've known Tim for years. You can't be the honesty and integrity that he provides in this auto repair industry. I highly recommend! -AT

I had a couple things that I needed taken care of on my truck and it was finished the same day. Super convenient. They're a great crew! Thanks Tim!

Certified Auto Specialists were very knowledgeable in working on my Classic Auto. They went out of their way to solve the mechanical problem and find the correct parts. Their service was First Class and Timely

A friend recommended I give this company a try and I was very pleased with the service and their work.

Tim and Kyle are the best most honest mechanics I know. They really take care of my Nissan titan pro txt and my wife Lexus IS250.

These guys are awesome. They do all my oil changes and I do one every 6 weeks with the amount of driving I do! If I have any issue...I take it to Certified Auto Specialists. The company I work for trusts it's entire fleet to them.They know what they are doing!

Tim was great and knows true customer service

Certified auto is an exceptional company. They are both very professional in determining what your car needs, and will help with finding the price to fit your budget. Great guys and have built an exceptional company.

What a great, trustworthy team!! I feel so confident leaving my car with Tim and his staff. They do great work and keep me updated on their progress. I feel their rates are competitive and that they only do work that is needed to keep my car in top notch shape,

Tim and his team are great! Great work, knowledge mechanics, fair price...what more could a consumer want in a shop!

These guys are amazing. Let's be honest, anytime your car breaks down it's a stressful experience. However, having Tim and Kyle as my family's auto mechanics makes a horrible situation so much easier. I never have to worry about being lied to with these guys. They let you know your options up front and you can tell they're doing their best to look out for their customers' best interest. They're honest, caring and truly make me feel safe when my car is returned to me. Thank you guys for taking care of us and going that extra mile.

I have had a lot of things done to my car including regular oil changes... they are absolutely awesome... I would never take my car anywhere else. I trust them completely... not like other experiences I have had with mechanics... even the dealership! Thanks Tim!

Awesome customer service with honest people not trying to over sale anything. They will tell you what needs fixing. I brought my car in the once thinking I needed a new fuel pump and it runs out I was out of gas and my gauge just stopped ready my gas correctly. Anybody other shop would of said they fixed my fuel pump to gain extra money. Honest guys done here.

They fit you in when they can. fast. conservative about time and money they work with you they are people friendly. I love Thier work they are the best I will always take my vehicle Thier

They provided quality service, competitive prices, and great customer service! I will definitely recommend them to friends!

HAD SOME WORK DONE HERE AND THEY DID AN AWESOME JOB. I WOULD HIGHLY RECOMMEND THEM TO ANYONE.

Great service and professional dependable place to have our vehicles serviced.

Tim and his crew are fast and courteous. They appear to love what they do and it shows in their work!

Work and service is always carried out in a professional and customer friendly manner. I'm always ready to recommend Certified Auto Specialists to friends. Service that can be trusted.

Great service

Always helpful.

When my strut blew out I remembered seeing the sign for Certified Auto Specialists near my home and figured I'd give them a shot. Tim and company impressed me. They had good prices on quick, quality workmanship. From my perspective they're honestly invested in their company, they want to do good by their customers, and they stand behind their work. I had them fix a few other things I knew needed attention, and left satisfied it was all a job well done. I'll be back. Highly recommend.

The guys at Certified Auto Specialists recently worked on my truck. They did a great job at a fair price. Consulted with me about my issue, offered to diagnose before "spending any money", called me to approve the work and consulted me on the best course of action for resolving the issue, and got it all done at a resonable price. Overall- I am very pleased, and will be back!

I am always pleased with the work they do on my car.

The owner has been my mechanic for several years. He has always provided professional service and will stand behind the work done.

Fast, friendly, reasonable, and honest!

Tim and Kyle are both outstanding. You never have to worry about them attempting to do unnecessary work to your vehicle. Very honest about what does and doesn't need to be done. Couldn't give a high enough rating for how good thesebguys have taken care of my vehicles.

Very helpful. Did not try to do anything unnecessary. Seems extremely honest. Will use him every time I need a mechanic.

Service could not have been better. Very fair price. Quick in and out, Everything my car ever needs will be done here.

Prior to finding Certified Auto Specialist, I had a new clutch put in my 350 Z approximately 18 months ago. I never felt like it was right, but was told that it was new and would take some time getting used to. When I explained my concerns to Tim & Kyle, they went in and found some shoddy work by the previous mechanic and got it running like its supposed to. In addition to the Z, they have performed service on a Honda Accord and a Lexus 460 for me as well. They do great work at reasonable prices.

I was referred to Tim and his shop by a fellow coworker, and the thing I liked the most about the shop was how honest Tim was with me. He was very professional but also easy to talk to when it came to what I wanted repaired on my car. He gave me his honest opinion on what I should do and what I needed to fix and quoted better pricing than what most shops would charge. I will not go anywhere else with my vehicles.

Our family "stumbled" upon Tim and Kyle's garage about 2 years ago....wouldn't evne consider another garage now !! Conservative, informative, reliable, reasonable, professional and always there to help! Trust Certified Auto Specialists!

Certified Auto was highly recommended to me by several coworkers and friends after a less-than-satisfactory experience with the dealership's service department. Time and time again, Certified has exceeded my expectations by delivering quality service at a fraction of the price quoted by the dealership and other shops around town. Rarely have I found myself saying that I trust a mechanic, however I'm this case, I trust Certified 110%. Words can't express how much their hard work and honestly are appreciated. Highly recommended!

Quick turnaround on complete engine replacement. Best price available. No need to shop around in the future. I will always go here for repairs and maintenance.

I am always impressed every time I bring my vehicle in for service! Very professional and efficient. Mr. Hayali is always courteous and informs you of anything going on with your vehicle! Hands down- BEST experience ever! Thank you Certified Auto Specialist! Keep up the great work!

Great to work with and timely repairs!

Absolutely the best repair shop around. Honest, dependable and fair pricing. Tim is always a pleasure to deal with and works hard for his customer's satisfaction! We wouldn't think of going anywhere else.

We have known Tim for many years. His work is exceptional. We place great trust in any work he has done on any of our vehicles. We own an m35 Infiniti which Tim has handled all the work since it went off Infiniti warranty. All work has been totally satisfactory. We recommend Certified Auto Specialists to everyone we know who is searching for a fair and talented auto repair shop who can handle their business at a fair price.

The guys at Certified have always taken care of me and my car. I think they do a great job and feel that they deal with me honestly.

Great service every time. There is no needless charges on the bill. They tell me what my car needs. They do not tell me every time I come in that my cards needs another $500.00 worth of work. Thank You guys

These guys service/repair every vehicle in our family. They are extremely knowledgable, honest and fair. I never worry they're going to try to sell me something I don't need. I can't say enough good things about these guys. I will never take my cars anywhere else. Chris B.

My truck was ready when they said it would be ready...everything was great. Nice to know you can have honest people taking care of your cars this day and time. Highly recommend to anyone needing you vehicle worked on!

Quality and honest workmanship is rare. I 100 % trust their guaràntee. Wonderful experience. No problems. Great job. Reba

Always reliable and always willing to answer a question. Great service, great friends and wouldn't take my car anywhere else!

Took my car to the dealer, Bob Howard Nissan. They said it needed a transmission. I brought my Nissan to Certified Auto and they found out the problem was a bad sensor that cost less than $80. Replacing the entire transmission would have solved the issue, but I never would have known the issue could have been resolved for much less money if I hadn't brought my car to Kyle and Tim. Thanks again guys

Very knowledgeable staff. Dealership quality work without the high prices

I needed a simple oil change on my 2004 Tahoe and Certified Auto Specialist made time that day. When my Tahoe started leaking oil, they got me in and told me it needed new gaskets, how long it would take and the total cost. Their price was very reasonable. They had my Tahoe fixed later the same day. I would not trust my Tahoe to any other auto service company. They treat me like a friend and not like an open checkbook. I want to recommend Certified Auto Specialists to all my friends and family.

They have always completed the work professionally and quick. It's nice to get the work done right the first time and at reasonable prices. Diagnosed a bad brake switch was causing the start button not to work and they figured out the problem in minutes. Would recommend to friends and family.

man what a place such expertise at every turn fair price for exceptional work if you need your vehicle worked on don't waste your time taking it any place else go to certified auto specialists you will not be disappointed thanks Tim!

I love doing business with Certified. The guys are great and very knowledgeable. They do not waste time or money. They find the problem and fix it not just parts replacers. THEY KNOW THEIR BUSINESS.AAA+ You can give my name and number if anybody has questions on how you run your business.

Every time I've been there I get treated like I'm family and get fast and quality service

Grear service , very knowledgable

I have been sending a lot of work here on all three of my vehicles and am very satisfied with the quality of the work and the personal, friendly service and timely completion.

Tim, always appreciate your timely and complete service. Thanks, Dale Wood

Tim is great. He was able to diagnose what was wrong with my wife's car after another shop told us it would be a $1200 job. Tim found that it was just a small $8 dollar part and was able to get it quickly installed. Great work and very trustworthy.

I have use Certified Auto for a year to service two trucks and two cars for both repairs and regular maintenance. Tim and Kyle give nothing but the best service at a fair price.
