This is a 2007 Mustang GT Premium with an all-aluminum engine, limited-slip rear differential, and traction-control override. Prior to me taking ownership the exhaust was upgraded to Pypes X-pipe and axle-back muffler delete straight pipes. This car has been reliable and low-maintenance. Of the few things that it has needed the windshield has been replaced and is still like new. The front wheel bearings have been replaced and the oil changes and rear differential fluid changes are up-to-date. The car has never been wrecked or smoked in.
