my opinion
I have a 99 WS6 Trans Am. With some minor tweaks and upgrades I have about 380 hp. I too thought the exact same thing as far as fun. However, I recently got a new job which is a 40 mile commute one way. I had to make the decision based on a more econimical standpoint.
While I could go get a Toyota echo, I still wanted to get a car I would enjoy. BMW seemed to fit the bill. I like the G35's and IS300's as well. But BMW is more trusted at this point. I may get my wife a G35. But she wants an automatic cuz of all the traffic around D.C.
Anyhow, back to your question. Why are you getting rid of the Camaro? I wish I could keep my car and get the Bimmer but I can't afford it.
While my car will be in here about 3 weeks, I KNOW it won't come close to the speed my Trans Am has. However, I do believe they handle turns better. Plus, with the 330i PP top speed is 155. Although it'll take forever to get up that fast. As for the torque, the Bimmer won't come close.
Just a point of note, a 2003 M3 did try to race me.

All he saw were my tail lights.
