Any pampered car will perform well. You probably got lucky.

But judging from the past posts here on Tsikot, the majority of owners can't seem to get rid of theirs fast enough, due to horrendous parts cost for what is, after all, a GM car.

I did try an E46 BMW once. You are right, it's very jumpy. But then so is the Mazda3, and I have no complaints with that.
