AutoNation Chevrolet Laurel

I took my 2005 envoy to this shop because of my brakes. they tried to charge me 1500.$ I called the company that fixed my brakes before this they charged me 600.00 for the same job. the reason I know they overcharged was when I told them to out my car back together, the repair man stated if it was a question of money-they could work something out. In addition, they denied the repair claim to both of my extended warrentee companies. My brother who was a mechanic for GMAC for 5 years stated that what they claimed could not be true. I had a tow truck there in several hours. the dealer put my car on the road- not completely assembled. when the tow truck dropped at the other repair shop all of my tires nearly came off the vehicl causing further damage. And they \charged me 100$ for their time. I would never under any circumstances recommend a GMAC vehicle again because they state I have to use their services, and because of this service rendered.When I bought the vehicle, I was told any reputable mechanic.
