If it makes people feel better my xkr is only £220 a year to tax, its the advantage of buying pre 2001. Anything under 1600cc is £100 and something. Anything over 1600cc is £220. Regardless of if its a 4 pot or a v12 with twin superchargers that only does 2mpg. I'm very happy with the amount of road tax I pay, and I'm in the safer bracket. I'd be more concerned if I was in the 2001-2006 age bracket, as the plan was to bring them up to the same level as post 2006.
