MustangForums.com - Need Help/Advice with 93' 4cyl 5spd

Long story short, had a truck neeeded tranny and motor ended up trading it for a rough 93' 4cyl. Cosmetically its not so great but what sold me it runs like a new sewing machine.
This is first mustang ive ever owned but am familiar with the 05' and up. not so much with these 2.3's .

Issues: 1) The car was originally red but someone very unprofessionaly sprayed it black. Not really wanting to strip and repaint im ondering how i may be able to get some gloss out of it . Polish? Wax? any remedies you know of?
2) The interior has alot of missing pieces and the guy did an automatic window upgrader on right side but left the passenger manual. driver side is missing door latch. and the steering wheel/ignition shroud is missing.
ALSO im not sure if this model had a trunk latch button in the cab but im hoping it does becuase theres no way of accessing the hatch with a key ( key fob is missing). how can i open the hatch without breaking anything. And where do you know of getting some interior pieces fro a good price?

ALL ADVICE IS WELCOMED THANKS!!! ELL ME WHAT YOU THINK IM ONLY 500 IN IT. DID I GET BURNED?
