As Lee says breaking the car will fetch you some nice cash. Don't forget you've got suspension, exhaust, seats, plastics, lights, panels, brembo callipers, glass, and so on. Best thing to do is sit down and list 50+ items of desire and gauge some prices by either chatting nicely with Lee or searching the web including eBay. Even the shell would be good for someone somewhere? Advertising main components is key, the more people who see what you have on sale the better. You could even try my350z.com and with their audience you'd possibly get some interest? I would although investigate with Lee a possible engine transplant. It would be a shame to lose your car just for it to be vultured.
You could even try and adverse on drift forums and other race listingfs to see if anyone is looking for a shell?
