Sounds like your wife and I drive the same way! She needs a Miata! I've never spun mine although I have done some (unintentional) sideways sliding. You just can't help yourself in those little cars-they are too much fun to drive fast!
Banking and fast small cars - you have a lot in common!
She has a A4 S line Quattro right now, it's pretty hard to get sideways unless you are Walter Rohrl:
