Welcome, jordanb.
I do not have a Turbo, but can certainly speak about the car in general. For the size of the car, the B200 is very stable at highway speeds. I remember how fast one can boot a car on the highway traveling north from Toronto to cottage country.. . the B will certainly feel very stable and safe.
If you read through this forum, i know that there have been a number of issues with the lamella panoramic sun roof. IMO, it's a nice to have. We avoided choosing that option because of known (although they may have been fixed by now) and possilble future issues with that option. Being in Toronto, you might want to think about the heated seats option, although I believe the Turbo models come standard with that.
If you don't have to wait for the 2009 models - which should be coming out by late summer, I believe, the 2008 models have some great financing and lease rates going on right now.
Overall, again, for the size of the car, it feels like you are driving a much heavier and bigger vehicle.
Good luck and do let us know what you end up getting. There are some pretty good and informative guys around this forum.
Cheers,
