I love my S2000. It is one of the most fun to drive cars made....at any price. I would recommend it highly. The long term reliability worries me a little. Not the engine, but other parts like the clutch, diff, and cv joints. While, I have not had any problems yet, my car only has 14.6k miles on it. It is my daily driver, rain or shine. The car is rattle free, looks great, with the hardtop is a decent daily driver, and has good performance.
Convertible, build quality, high revving engine
high revving engine is a double edged sword. A larger engine (2.5 liters or so) would make it as fast, or faster, and easier to drive fast all the time.
