Purchased a chevy malibu a little over a year ago with the help of a cosigner. At first I thought it was great, found something within my budget. However, now... not so much. Whoever did the putty repairs at their service garage really knew how to hide the rust holes and put the inspection stickers on it so it could sale! It won't pass inspection now bc of the rust damage and I'm still owing on my loan. I also never received my gas door/cover that's in the contract/warranty they gave me stating they would replace it. They ordered 1 and it was the wrong size and shape, was told I'd get a call when it came back in, never have! Called twice about it myself, never got a call back so said screw it... Out a gas door and out a car again... Save your time and money, DON'T buy from here!
