Probably the only one of my previous cars that I'd buy back given a chance. 20 grand (£) is too much though!
This one's a bit special. Not many 8 Litres about - I think a certain Jay Leno has most of them and has transplanted their motors into other chassis. http://www.vintagebentleys.org/carpages/gw1571.php
A few years ago, Audi and Bentley filled the podium at (IIRC) Le Mans and the commentator remarked "So, that's a 1, 2, 3 for VW!" ...
Mk 9s aren't too common, even over here. Mk 8s are ever rarer, hence my assumption that it's a 9 - they're identical in appearance apart from the boot badge (and there are probably a few 8 with 9 badges to make them look newer!)
