Total quality, total price, Cartech worked with us that I can't give them a high enough recommendation. They are awesome. I couldn't ask for better service. They were timely on their repairs that I did. Nothing but the best. I would never bring my cars anywhere else but Cartech.

I would recommend them all of the time. They are very trusting, they will tell you exactly what is wrong and what it will cost.

Mike is always honest and fair. He does his best to work with your schedule and make the most out of what is usually a not fun experience to have car repairs.

He is the bomb diggity. He is honest and cares about the people who come to them. He leaves no stone unturned. When you leave you have a safer vehicle because of him. He is trustworthy. He is a very top notch mechanic. He doesn't do anything without telling you. If he doesn't know he will get someone or get a third opinion so it is the safest when you are on the road.

Honest. Friendly service.

by - Verified Customer March 19, 2015

The staff was friendly and knowledgeable. He knew what he was talking about. He had me in and out in the time table that he told me he would. It's close to my house.

They are trustworthy, honest and they do very good work.

They are very good there. They are satisfactory there and I am very happy with them. They have good service.

by - Verified Customer February 25, 2015

The service was outstanding and the other reasons is that if it isn't broken they won't fix it. He asked him if the brakes should be replaced. The owner explained that the brakes didn't need replacing. He had a lot left on the pads. Even in a normal garage the brakes would need to be replaced. Whatever parts that need to be replaced. The owner will show you the parts that need to be replaced afterward. Just the honestly of the shop is what I appreciate.

by - Verified Customer February 12, 2015

He is a good honest mechanic, he doesn't try to rip you off. They are timely, they get to your car in a reasonable amount of time and they do very good work.
