I love the Jag on the back, but why not use the blue, stippled maybe, from the webaddress as the track colour and leave the car (with wheels and shadows) in purple
I think the stripes would look better without the 2008 on them (we have the year dated on the "tag" badge anyway) and with the proper club arnage logo that is on the sleeve in the top of the stripes area, as suggested by Mark.
But whichever the Jag looks stunning and follows nicely after last year's Ford
Nostalgia being what it is it'll soon be time for the no 7 Bentley...
