I've struggled with this from time to time. My once-ownership of a sports car was back when I was 22, living in a remote mountainous area with a lot of twisty two-lane paved road with very little traffic. So I could really play and did so. Further, if I happened to substantially exceed the limit, the local deputy (who pretty much knew everyone) would probably have shaken his head and given me what-for before cutting me loose.
Whenever I think of getting a sports car today I wonder what the purpose would be. Shy of a track, I'd never have the opportunity to really test the performance and handling. Even were I unwise enough to do so, the penalties these days would be a much different story, not to mention the embarrassment of being way past old enough to know better! Not saying that's wrong or that it was ok back then - that's just the way it was and is. But it does manage to keep me away from the dealer and my wallet in my pocket so there's an upside.
