Thanks Ferni... I know we've talked about this one already... heh.
I suppose at the end of the day it comes down to getting the car checked thoroughly. Most of the ones I was looking at have aftermarket pod filters, suspension, rims, the odd one has BOV, etc.etc.
A couple have got aftermarket computers and new turbos.... I'm steering clear of those that look like they've modified the turbos for the most part for that reason although I will inspect any GTR that looks reasonable. Cost is the number one prohibitve thing for me right now anyway.
