True, the V8 has 15"x7" but he doesn't actually say they are stock, just that they came off his Soarer when he bought it. I don't think he really knows what they are in size. He has now posted that they are 16.5"x8". I've never heard of a 16.5" rim before. What tyres would fit that?
I still think he's got the right idea: SELL THE BASTARDS.
