Hey F360,
I'd definitely be interested in a Vanquish on the XK and was also thinking that there would be money to be saved on quantity orders if a few people were interested. Would depend on the kit though, the ones I've seen like the Ash Mart Kit and the vanquish replica being offered by exclusive tuning worldwide/fibreglass.de are pretty good but dont represent anything like the accuracy of Extreme's Ferarri and Lambo Kits...Unfortunately its an Aston Martin I want, I'll never be able to afford the real thing and it looks like no-ones going to build an exact replica so guess I'll have to settle for something that looks "good enough".
Keep me posted on your progress because I definitely want to get started on my kit some time this year.
