Bought a Mercedes c450 from there. I was talking to Richard and said the car is in perfect condition and everything.and I couldn t get there to test drive it before because I was far away. But when I get there my brother notice there s a bubble on the tire. I drove the car the brakes made noises I told him he said take it to the dealer and get it check anything wrong with it. They will cover it. Now every time I called them they say they will get back to me.
