G60 BBS

I have recently bought a Corrado G60. I have a friend with a 16v model who said i can buy it for spares. His interior is mint (black) mine is grey and the drivers seat is worn through, so i will probably buy it just for the interior (v' cheap). My question is how many other parts are the same how many other parts can be used from his 16v on my G60? Much appriciated..
