eh in the right hands i'm convinced any car can be driven quickly around the twisties.
that being said, i'm one of the less skilled drivers on this site, but given a decent pair of shocks and some azenis, i think mine would be pretty damn quick (with the right driver

).
EDIT: little disclaimer on this one, this is more for autox, not road courses... my car is severely underpowered in the road racing department.
