I got stung by expensive tax. No difference between a 07 and 06 facelift apart from the tax. Saying that though, insurance is so crazy that I would definitely buy on condition rather than just wade into a 06 for the sake of a couple of hundred quid a year if you can't find a decent one. I wouldn't rush to trade my 07, but I'd probably be looking at a 2005 rev 3 if I bought again.
