Check this out: http://www.qv500.com/adsvendorgtoproto.htm I remember seeing a pic of a yellow 288 GTO and I assumed it was a Photoshop job, but I guess not - it's actually real. Cool story behind it too.
Considering that at an asking price of 1.3 MM Euros (about the price of 4-5 of the other 272 GTO's made) I'd say that this car will be for sale for a while longer.
