I recently bought a new set of Coopers (forget the model) for my wife's Mini Cooper. However, that was really only because she liked (read "insisted") that they continue to say "Cooper" on them to match the car.
That being said, they have been a great all season tire. The first year we had the car it even saw a little snow as it was our only vehicle for a bit due to an accident. Both the car and the tires did surprisingly well in light snow/slippery conditions but they certainly would not match a true snow tire and we didn't drive it in more adverse conditions.
I don't know a lot about street tires but if you ever need advice on off road traction, feel free to ask.
