I have an '86 NA w\129,000mi(15,000 on new motor). The only addons are a RP Catback and a K&N drop-in filter. I think thats it. The paint and interior are in good condition except the sunroof is broke and there is a little front end damage but I plan on fixing that pretty soon. O ya, its not power windows or steering but there is AC.

 

Price will depend on the area you live in. Try www.kbb.com To me it sounds like you could get ~$2000-$2500 if the damage is fixed.
