I don't drive sports cars, but I have never considered that my Mk 1 has excessive body roll and the Mk 3 I had on loan was not significantly different (though I didn't throw it around as much as I do my own). I find it about average for the saloons I have owned, and considerably better than my Volvo S40. Modern saloons must have come a long way, if the Jazz is now considered poor for body roll.
