No mention of it that I can find on the RX8OC forum.
I did see an auction catalogue where it was shown as;
Lot 4003 Mazda RX-8 231ps Reg FM54 UXD
First registered 04.02.2005
Showing 83,235 miles (TAKEN AS INCORRECT)
This was at Bedford in March this year. Along with a whole host of other random stuff (bottles of whisky, wine, beer, computer stuff, TV\'s, watches, etc), so not a specialist car auction. There were only two other cars in the auction of thousands of items. A bit weird!
