In the UK, ALL 150PDs are badged GTI (red I), that was VW UKs choice over the all red TDI. To be fair, the TDI in terms of performance is more worth of the GTI badge than the 150 petrol.... the 150 1.8T should have merely been badged a GT or something similar, with the GTI badging saved for the 180 1.8T.
Hmm, that's strange, i've never seen ANY diesel badged as a GTI! [:O]
Secondly, i disagree with the next statement about diesels being more worthy of a GTI badge THAN a GTI! [:|] How can anyone consider a diesel to be better performing than a petrol, now okay they have more torque (which is a big plus i suppose) and as far as diesels go, they have come along way from the black smoky things they used to be and not that far behind petrol cars in terms of performance, but petrol will always be the better performer. Period!
But still, i'd sooner stick with my good ol' 1.8T than ANY diesel you could ever offer me! You say you only lasted 10 months with yours because it was a bad all rounder, yet i haven't had ONE single problem go wrong with mine yet (touch wood) since i've had it! [H]
Finally, i think it's unfair to say that the 1.8T 150bhp should only be badged as a GT. Ok the 180 is superior to it, but that doesn't make the 150 inferior does it?
Still, like you i'm only voicing MY opinion, and i hope it doesn't cause offence! [
