FWIW, Dave, you and I have a lot in common. I too have always loved a Porsche 911 (is there any other kind of Porsche?). I have always wanted one and got to drive one a time or two when I was a valet but never on a track or on open road.
However, I am seriously frugal when it comes to cars. I think they are one of America's worst wastes of money 9 times out of 10. The largest drain financially for the littlest return. Horrible invest, etc, etc. Except that I can appreciate a nice care, although I don't think I could get myself to spend the dough unless I was filthy rich, which isn't going to happen.
I am actually a decent driver, fairly natural for me, one of the few natural athletic abilities I have besides my hobbies of course.

I am still too practical when it comes to cars, but I would rather have an off road excess than an on road excess.
I did use to have an obsession about my cars until I move to NYC, and NYC broke me of it. West Coasters can't understand, because they haven't live it. I use to be that West Coasters, now I'd rather sit on a bus and read my paper on the way to work and not spend money on something some poor parker/driver is just going to dent when parking next to you.
