I had one for a year and a half.  It handled like a dream and was extremely quick, provided you pushed it hard.  I didn't drive it enough to warrant keeping it, however, and it was NOISY (the downside of having to push it hard).  
They're a great, fun, impractical car (just like convertible sports cars are supposed to be) but you've gotta love driving more than listening to music, having a conversation or preserving your hearing.
