1991 Ford Mustang GT 5.0 5 Speed Grey Interior

1991 Ford Mustang GT 5.0 5 Speed Grey Interior. Condition is Used.
I have put in over $2,000 since December on Tires, Air-Conditioning, Rear Brakes, and adjustable clutch cable.
Only thing that doesn't work is the heater. There is a small leak in the moon roof and the source has not been identified yet. Clutch cable went out on me and I replaced it with an adjustable cable. New clutch was installed back in 2015 or 2016 with a stiffer clutch. Weather stripping was replaced in 2017. It isn't driven in the rain, taken through the car wash and it sits inside the garage. Pretty sure its been in the south most its life. Odometer read over 46k. This is incorrect based off a Carfax I had done up on it a while back. Any questions send me a message.
