Help... Vin #'s dont match
Read this entire thread today, and talk about psychotic. Getting any "authorities" involved is the last thing anyone should ever do (I know this from personal experience). The car would wind up crushed and the OP would never get his money back. The car looks pretty nice for the one pic we saw. $9,000 for a nice numbers matching 340 car seems like a screaming deal in these days of overpriced muscle car madness, so when it turned out to not be the deal it's really not a big loss. I'm sure you could turn around and make money off it in a heartbeat from someone who isn't a stickler about numbers. Hell, I'd give you what you paid for it.
If you bought it in the mindset that you've always wanted one, and you had a major let-down because it's not exactly what you thought, then I feel bad for your situation. If you bought it to clean up and flip a few grand more than what you paid then no sympathy.
