Ah, that's an old boxter, no supercar in my opinion. All is well on first supercar sold for bitcoins, as long as one of you guys puts up some coin before a local craigslister does. I'm also assuming he paid $9,000 fiat, unless he really got ripped off ($150,000+ USD for an early '00s boxter?)
It is very obvious if you read the thread of comments. One person says "Yeah, that looks like an (very) early 00s-era Boxter (non-S). It's probably only worth ~$12,000.", to which he responds "spot on chief, I got it for 9288, my dad is a good haggler."
So, yeah, $9,288 USD. Nice car though, I'd drive it!
