Personally, I'd get it running well. Replace/upgrade parts that can be transferred to another vehicle (which is pretty much anything), but don't go all out. This way, (1)you still have a dime, (2)gives you time to look for someone w/ a rocker or a donor car w/ one OR (3)if out find a cleaner dime, you already have good parts to transfer over.
DON'T scrap it. Hell, I'll buy it off ya before that. :)
