ty.. its just an extraordinarily well made model.. to my knowledge nobody has actually tried to do it yet, every so often on ebay a "kit" shows up on ebay to convert the VX.. but it will be far from bolt on im sure... silverbullet75 built the model, you could try PMing him and see how difficult it was on the small scale

also heres a thread about it
http://www.vehicross.info/forums/sho...ght=lambo+door

if you look at the bottom of that thread, there will probably be links to other related threads about door conversions (this is true of any thread, related threads show up at the bottom of the page)
