Not even 1500 miles into the "oil Change" my vehicle now needs a new engine. I don't know if they changed the oil to hide the problem so i wouldn't see that the engine was shot or if it just happened that way. Either way, I called, 6 weeks after I bought the vehicle, willing to bring it in to whoever they would like to look at it themselves, and they will do NOTHING to help fix the problem. Actually, they don't even call you back to let you know they arn't going to help. I understand buying a used vehicle is always ifffy- but c'mon, I should have gotten more then 1500 miles out of it! They say the law says they don't have to do anything so they won't. Lot is probably FULL OF LEMONS!!!!!! BEWARE!
