There really are some aliens out there. I haven't analysed what they are doing, but the laptimes on some of the servers I've been on are amazing.
Anyway, here are my best GT times which I've managed to pick up from my 'Career.blt' file. I don't drive NGT that much.
Barcelona:
1:40.972* - Lister
Brno:
1:56.290 - Lister
Donington:
1:27.826 - Lister

I've only done 20 laps of Barcelona.
I've now moved on to the Saleen which has a beautiful in-car sound.
