I never answered to this topic...

So here's my answer. As far as modern street Alfa's is concerned my fav. one is 156 GTA. Aggresive, serious looks, superb engine, amazing handling(considering that we'r talking about a car with 250bhp in the front wheels), vgood quality. Ohh and of course the option to turn VDC completely off.
Now, as far as modern race Alfa's is concerned, my fav. is 155 DTM. You know, that red one that used to roar through the DTM racetracks.
