I purchase a GM certified used vehicle from Gwatney and it's been the worst purchase ever. I drove all the way from St. Louis to get the car. When I arrived the car was FILTHY. The car had buttons jammed into the console, finger marks on the ceiling, dints on the door. I was told by the salesman (Mr. Masengil) that it was in PERFECT condition. When I got it home, I found out the tires were fault (had to get 4 new tires), shock and struts had to be replaced, there were seeds and crumbs in the headliner, the sunroof was leaking into the car, the airdamn was missing, the steering column is popping, the headlight was leaking, the passenger door lock was grinding, the rotors were warped and that's just just to name A FEW! They lied to me about the "features" on the car and they added EXTRA FEES without telling me! DO NOT GO THERE, UNLESS YOU WANT TO END UP LIKE ME!
Cons: THEY ARE LIARS AND ARE LAZY
