In response to something that happened in another community, the Team behind AstonMartinLife has begun setting up a specialist site for the bespoke Supercars covering:
Jaguar XJR-15 & XJ220
Pagani
Bugatti
Spyker
Mosler
Koenigsegg
and a few others.
The site is now live but not publically launched yet as he is still working on a few of the aesthetics.
Please take a look, join, add a few posts, and lets help get it off the ground.
