Sorry to hear this project not get finished.... but as time goes on... little things like car projects don't seem as important that's for sure. After all the work you put into it you should simply pay someone to finish the damn thing and get some satisfaction for all your work/effort/research put into it!
If you total up all the paintwork, low mileage car, suspension bits, big brakes, rear diff setup, rims/tires etc..... even without an engine/trans this is a good deal for a buyer. I would like to see the complete parts list.
A low mileage car with perfect paint (it won't be since it is 15+ years old) is probably $7500. Then that whooshing sound coming from your pocket is the money flying out of your wallet for upgrades. A nice quality paintjob with the engine bay/door jams done is easily $4-5K. So if you buy a car with faded paint for $5K, add another $4-5K for paint... you still won't have half the upgrades this car has unless you have crazy hookups and a lot of time on your hands to do it all yourself.
Good luck with the sale! Bummer to see it go.
