On the weekend i took the plunge and Bought my 1st Jag. Im loving the ride, the quietness etc etc you know, all the things that Jag owners enjoy :) However i need some help with something. The VIN etc all bring it back as a Portfolio S on a 12 plate with 272 BHP however when i paid for the road tax it came back as £137 for the 6 months which equates to 169g/km or a 240bhp engine. Is there any visual difference between the 240bhp and the 271bhp? I'm worried that the engine has been changed on it in the past. I don't have the V5 yet so cant check that.
