Baic not trustworthy!

I went to baic wanted to trade in my Kia SUV, While I was test driving the X55 Beijing and changan. They took the car for observation and test driving. When I came back their report said that Mechanism of my car is perfect the only thing that needs attention is the paint of the car. To a nasty surprise, when I drove back home my car was shaking, making sounds that were not there before, I contacted them to let them know they said it has got nothing to do with them, the kind of treatment I got from the company,boats were missing in my car the coil pack cover was not there, I do not recommend this company
