The closest I've got to a Cooper S so far is looking at photographs, and I live in the country where they are manufactured!
Your comment about the MINI not being up to BMW 3-series quality is a bit surprising, since from my experience the MINI seems to be a match at least for low end BMW/Audi quality, if not the high-end products. (And I've owned an Audi A3 in the past which is the VW Golf equivalent.)
