Mixed feelings. Didn't get a pretty important phone call back and the diagnosis was incorrect.

They have always done excellent work for me.

by - Verified Customer May 14, 2015

They are excellent, and they always do very good work. I have never had any problems with them or their work.

by - Verified Customer May 12, 2015

I never give a maximum score because there is always room for improvement, and their prices are a little too high.

by - Verified Customer May 05, 2015

You guys are good but can be expensive.

by - Verified Customer May 05, 2015

Both major problems I have had over the last year do not seem resolved even after considerable expense and time. Dash panel indicators are still lighting up!

They do good work, and they are always very fair.

by April 17, 2015

I think they are good, but they have a tendency to be expensive and they recommend more work than what needs to be done.

by - Verified Customer April 17, 2015

They have what I would call a discount card, or plan. You pay a quite reasonable amount of money for the card and in return get freebies for minor maintenance and discounts on other procedures. In my case, the card will easily pay for itself. Also, the work I have had done was good.

by - Verified Customer April 15, 2015

They are very trustworthy and I like them. I can take my car in there and they won't try to tell me that I need services that I don't need like other places I have been to.

by - Verified Customer April 08, 2015

I actually know some of the mechanics, my friends do my work. They give me a great deal and the work is done on time.

I like the friendly service, I am always satisfied with their work.

by - Verified Customer March 26, 2015

At first I thought MM to be different from other auto repair, more honest, more genuine. Last visit I was disappointed to find that they just generally like to run up my ticket as high as they can while trying to convince me that I'm getting a good deal. Will be on my guard next time. Not buying it!

by - Verified Customer March 20, 2015

They seem to be honest and very knowledgeable of the service, overall I like the experiences they provide.

by - Verified Customer March 20, 2015

They did good work and they were pretty nice. They are very friendly and accommodating, they knew I needed to get in and out quickly and they did whatever they could to make it happen.

by - Verified Customer March 17, 2015

They did what I asked at a reasonable price, and did their job right. They are competent and know their stuff.

Great customer service.

by - Verified Customer February 10, 2015

I would never recommend Master Mechanic to a friend or colleague. In fact, I have recommended that friends and colleagues stay away. I took my car into MM because a check engine light was on; after keeping it all day, a $1200 repair estimate was issued, for something that was not at all wrong with my vehicle. A different mechanic located the actual issue and repaired my vehicle for a third of what MM quoted. Dishonest.
