When you can take a Countryman S out of the box and run gravel back roads at 100mph+ sideways and for hours at a time, I would say they handle pretty good. When they can take a 5.0L Mustang in the 1/8 mile from a standing stop, that too is pretty good. My only complaint is that the front door could be a little bigger for getting in and out. Just no match for a tricked out R53 S.
