I still am dying to know how fast I can go on my car. The factory speed limiter is set at 155 mph, but I don't feel daring enough to make it go that fast. Maybe I'll decide to hit the track someday. I don't think I've even hit 85 mph on my car yet (sad, I know).
On my E36, I have gone as fast as 125 mph (indicated), and that was pretty fun. Just like you described, DSky, my car also felt very stable along the way
