Neither the M3 or the Audi can beat the Porsche in a straight line, however the Audi has been said to outhandle the 911 TT on the track. The writers are all saying that when they tested the Audi in Italy (Modena, Maranello, etc), the car got WAY more look from bystanders than the Ferraris and Lambos (indigenous species in those parts). That definitely says something...
I had an M3 circa 1998 and it was a great commuter car, but nothing... in my mind... will ever come close to competing with the Porsche. Of course, I am quite biased since I own 2 of them (plus a Mercedes, plus a Chevy Tahoe for pulling the toys...).
But... the Poll says the GT3? That's a cheap Turbo! I would save up a few shekels and take the 911 TT over the GT3 in a heartbeat.
But... the GT2 is the REAL supercar. Ridiculous horsepower (530), 2 wheel drive, crazy fast (200mph +)... but too bad they will only be importing a few to the US this year.
If you think I'm full of shit (it's okay, a lot of people do but I could care less) feel free to have a look around my garage at
