around 110 in my 325i
125 in my bro's 95 240sx
130-133 couldn't tell was almost redlining in my moms 2001 pontiac grand am gt
115 in my first car before 325i: ford contour sport, had more to go in fifth
100 in my dads 04 toyota 4 runner: it felt pretty stable but I didn't want to get cocky driving that thing!
