All I have to say about Cottman is good because they were very good to me. I had another service center look over my wife's vehicle (2011 Hyundai Sonata) because she reported strange noises coming from the brakes and was afraid to drive. I was told that there was extensive front brake damage and new calipers would have to be ordered. It was also stated that parts for my particular vehicle were very expensive and, even with discounts on labor, I was looking at about $1200 (good thing the parts weren't in stock).
Looking for other options, I searched online and found RepairPal that pointed me to Cottman. The tech I spoke with didn't want to quote a price range over the phone but convinced me to come in for a free quote. I am so glad I did. The vehicle was diagnosed with bad rotors and the work (front and back) was considerably less than what was given to me by the other shop.
