I'm selling my 1999 5-speed 4.6 GT Mustang. The engine has been replaced with one from a 2004 Mustang (that had 50k-ish miles) and that engine now has around 80-90k miles on it now. Just did a recent tune-up about a 100 miles ago and the radiator, battery, alternator, and fan were recently replaced as well. Heater and COLD AC WORK just fine. Previous owner installed an ASC brand sunroof that no longer works but can be repaired with that same company and they're located in San Diego. This car runs and drives fine with no issues.    The car is on non-op so no past registration is due. The car will be sold smogged and ready to be registered. The driver's side seat does have a tear on the side, other than that the interior is pretty clean. Car does need a paint job but still looks good from 10 feet away. The only reason I'm my selling my car is because I have too many cars at the moment. This car has a few upgrades that have been done, here is the list: - Bilstein shocks and struts - KYB quad shocks - Cobra hood - Cobra front bumper - Side scoops - 4.10 gears - Rebuilt differential - Flowmaster type mufflers (sounds really good) - Pioneer stereo (Bluetooth) - Sound system - MGW short shifter - Cold air kit - BBK shorty headers - 18" FR500 rims with Nitro 275/40/18 up front and Hankook 285/35/18 in the rear - HID headlights (bright white)
