r32dood

I'm in the market for an r32 GTR. What issues do they suffer from? are parts expensive? easily obtainable? electrics a problem? Thanks. PS: Alll the grey import ones i see all have say 50,000-100,000kms on them, are these legit Km's or are they dodgy? Because the interiors do not seem like cars that i have owned that have done 100,000kms. PS: I keep getting emails from J Spec, they have some really cheap cars ie: $15K+, are they a good operation? Thanks again.
