I have had my mustang for a year and 3 months. It had 89,000 miles when I bought it and it now has 99,000. Since I've had it I had to put new spark plugs, a frame bushing ball joint, belt, a/c clutch, ignition, and also have had it aligned twice. The seats that came in it were ugly. But I put seats from a 99 Mustang in them which look really nice. I have magnaflow dual exhaust on it (which sounds great), and traded in the 15" rims for 17", got a new sonic blue paint job, custom taillights and headlights. Which have made it a good looking car that turns heads. It has been reliable and has never broken down. Overall it is a decent car.
The interior, the dual exhaust, the rims
Better gas mileage, more power, nicer standard rims and seats, more room, less little stuff to go wrong
