This review has a surprise ending (in the best possible way).
The best experience I've ever had with a mechanic. First, I want to make a special point of how friendly everyone was. Polite, professional, and kind at every step. The problem was diagnosed quickly. It was explained in plain English. I authorized the repair and it was completed within hours.
Now here's the kicker: the bill was less than I was quoted. I have never seen or heard or this happening. I was quoted a particular amount and expected to pay that amount. I didn't see that it was substantially less until I went to pay. I am blown away by this incredible act of honesty (they said it simply cost them less to repair than they expected, and they passed the savings along to me instead of pocketing it).
So in short, go to Martin's if you want extremely honest, highly competent service performed in a timely way, and if you want to be treated with the highest levels of respect and customer service.
