It was a nice experience. It's really good customer service.

Diagnosed the problem perfectly and saved me a lot of money for what I thought was the problem. Accel is as reliable as gravity when it comes to fixing weird old cars.

Accel Automotive is a wonderful repair shop. They complete work on time, explain thoughtfully and clearly what needs to be done, and offer a fair price for work completed. We highly recommend them!

by - Verified Customer November 20, 2017

Excellent experience - clearly explained, quality work, and done a bit earlier than expected.

by - Verified Customer November 16, 2017

I've been going to Accel for close to 20 years and have always been totally satisfied with their work. The prices are fair, I've been treated with the utmost respect, everything's been explained to me, and they've gone out of their way many times to hook me up with lifts to work or home (both places are nearby but other mechanics probably wouldn't have done the same thing. I've sent a number of people there and they've become regular customers, too. I'd recommend them without hesitation, no matter what you drive.

by - Verified Customer November 15, 2017

We are always satisfied with the excellent service.
