I second this. My 2006 Mini Cooper S convertible 6 speed is like a go cart to drive, which I love. It's a high RPM, not much low end low torque package, although it's got a super charger so it's little better (IMO) than the turbo. You wouldn't want to drive it over expansion joints all the time. Jar your teeth out! But get one with a warranty!
Really it depends on what you find fun. Corvettes and some of the MBs will really pin you in the seat with torque and go like stink. They handle well and have very good performance, but are not what I'd call nimble in feel. (The go-cart thing again.) S-2000 and even Miata's are fund but I have too long a torso to fit in one with the top up. Both of those are high RPM not much low end torque as well.
What makes a car fun to drive to you?

Third that. 2013 Cooper S. Maintenance issues seem to be getting better as BMW improves things.
