I'll consider selling my 2004 Audi TT roadster for BTC.
It has 130,000 miles on it,
Its silver, and a soft top convertible.
If anyone is seriously interested in buying it let me know and I'll post pictures and stuff.
I live in North New Jersey, and you would have to pick it up unless you wanted to pay extra for me to bring it to you.
Have you tried carlister.co? That's a site mainly for buying or selling of cars.
Alao have you considered selling it in your local for fiat? You could just buy bitcoins with it. Just my thoughts.
