NEVER buy a car from capital car deals,... they used to be good guys but now they are a bunch of D**ks! they are only there to rip you off!
a friend has an original golf diesel his name is Dr. Arif Aziz but i'm not too sure if he'll sell it (as he just got it),.. but give him a call on 0325169897 and tell him you got his number from Sameer. he might point you in the right direction.
I've been a big VW fan forever (2 superharged VR6 syncro Mk3's and 5 beetles,... serching for a microbus, thing & Ghia!)
