I have a 1989 Honda Crx SI with 76,000 miles on the body and a rebuilt engine about 17,000 or so miles ago. The car was just at a body shop so it has absolutly no dents on the car, and no rust on the corner panels or around the side skirts (ran me about $1000) heres a list of things the car has.
Full Bodykit- not on the car, the bodykits in primer with no cracks.
Intake
Ractive Headers
Hi Flow cat-catback exhaust
Euro Tail lights
Clear Corners
New Battery
Pyle Headunit
Logic competition speakers
Rockford Fosgate 12" Sub
2 amps, 1 is a kenwood, 1 is a boss
Reverse Indiglow Speeometer
5' Autogauge tach
DC Front Strut Bar
16" Rims

Also have a spare brand new head gasket

Problems with the car-
No headlights ($50 on ebay)
Could use front motor mount ($30)
Bodykit is not on the car
READY FOR PAINT

Thats about it.. all together i put at least $2500 into the car + invested.

Im really only looking for a price that the cars worth but if anyones interested let me know.

 

$800. with new paint about $1500

 

ef_you the car only has 76,000miles on it

 

$1500, maybe

All the mods you list are mostly wothless. The miles on the are are the 1 redeeming factor.

 

It still has a stock motor in it, No swap+not worth much, unless you are selling to someone not into cars. No one is going to pay alot for a CRX that they are jsut going to use as a shell, so like ef_you said $800 is about right for people that are into civics cause the first thing being done is that motor coming out. If you are just trying to sell in auto trader or something, the most would probably be $2500, but that would be if you put everything back to stock.
