Not mine, but I ran across this and thought it was interesting:
http://tulsa.craigslist.org/cto/4167760551.html 1973 Volkswagen Beetle (Std.) for 24 Bitcoins - $7000 (Tulsa)
Price is negotiable. We want 7000 in dollars because I value them less, but if you want a substantial discount, you can buy for Bitcoins.
I guess when it was posted, that was a substantial discount. Not so much today, though!
