I know what you mean about the bigger AMG models, a mate has got an E63 AMG, over 600bhp. he was taking the **** out of my 330bhp, I said '0-60 in the dry would be very similar, in the wet I would be pulling away from you, but from 60mph up I wouldn't stand a chance'
I'd like to have a go in an A45
a couple of years ago a mate got a new golf R, he modded that and easily got over 400bhp. never had a go in that either :(
