You Don't Have to Take Our Word for It!

Here's what some of our satisfied customers have to say about Certified Auto Repair Inc.:

Mark, Tracy and Randy are all great and really try to help you out with your car problems!

Laura O.

Honest, fair priced and professional. It is very hard to find a honest place now a days including the dealers.

Farhan S.

Small auto repair facility. Very honest and straightforward service. My repair shop of choice for over 18 years.

Cesar R.

Best shop around always amazing customer service. Appreciate the great work will be coming back.

Ronald K.

They have saved me thousands over the years. I wouldn't take my car anywhere else.

Devon H.

A++++! I've been searching for a good, honest mechanic for years. Mark is definitely that guy. I owned a 12 year old car and brought it to another place earlier this year. The mechanic would have charged me over $800 to fix and it wouldn't have solved the problem. Mark said it was going to cost me over $3000 and suggested to get rid of it instead. I've been taking all my other cars there and I appreciate the best price and honest advice. TAKE YOUR CAR HERE!

Paul K.

I definitely recommend Certified Auto. Mark, the guy in charge, is a really fair and decent businessman. He was personable and took time to discuss all my options and even showed me part price listings on his computer so I could understand the price break-down. Even though the shop was busy that day, he gave me personal attention and managed to fit my repair in the same day. Most impressive was that he offered to match a competitor's price using a BETTER quality part than they would have used. I would absolutely do business here again.

Felissia C.

I have used Certified many times over a 10 year period. Mark, the owner and his staff have provided excellent service and have been willing to explain repairs to me in detail. Mark is very fair and I would trust him with any repair. His track record is flawless. Mark has serviced my Dodge Caravan, Chrysler Town and Country, Toyota Sienna, Ford Mustang, Honda Civic and Chrysler PT Cruiser.

Chuck B.

Great friendly and quick service at a reasonable price. Brought my car in for an oil change and it was done in 20 minutes. They also refilled my windshield fluid and the air in my tires as a complimentary service.

Joe M.

Took my car here for a repair. Nice guys looked at my car right away. They gave an honest and genuine assessment and even showed me where the issue was. Even for issues that they were not servicing such as buying new tires. They helped me decide where to go and what would be most affordable. Very happy with my service!
