Wow, this took a rather unexpected turn into darker territory.  I sense the onset of a midlife crisis - it starts with the abrubt awareness of something you used to be able to do and can't any more, then it wanders into trying to relive your youth. I'm guessing you're toying with the idea of buying a sports car? I know I did, a Porsche 944, a car which was one of my favourites as a teenager and is still relatively affordable for me. I still look occasionally, because I've not yet reached the point of acceptance that I'm too old for such nonsense.  Sigh...
