Ooer, one more off to the dark side then!! No doubt you will enjoy the power but I'm wondering if you'll miss the style of the GTV and the sound of the Arese V6? It will be interesting to know what the differences are long term too.
M Divisions 3.2 6 is a stunning engine. Total masterpiece, but it doesn't sound as good as an Arese V6.. Not many engines do, but the BMW motor is the better engine (and so it should be, it costs loads more).
As for handling, ride, braking, the Z3M is going to be better than the GTV as well. But will it feel as special once you get used to the power? Only time can tell
It is awesome. I also got one with all the options so it has a factory hard top so its pretty close to the legendary M Coupe. I actually really like the sound of the M engine as well. It has a real grunt to it. Thinking maybe next year i will look at investing in an M6 if my mood is good.
Miss the alfa already but the Z3 M Roadster is a better car with a little more wow factor
