I recently took my car in to Bertini's to have it looked at. It was making some terrible sounds. I was given an estimate of $84.60 to determine the problem. Just a couple of hours later I received a call with an estimate of the cost for repairs. Although I didn't end up servicing my car at Bertini's (I serviced my car at a cheaper repair shop), I would consider them to be a great choice for quality work. You can often find a 10% off coupon on their website (Bertinis.com).
Price is not the lowest, but you can be confident that they will do a quality job. Additionally they seem like a straight up shop. When I picked up my car, they only charged me half of the estimate ($32.30) since the mechanical diagnosed the problem in only a 1/2 hour.
