Thanks, everyone, for your replies. As an update, I've agreed to buy this one:

The pictures really don't do it justice. It's a superb car. And the price (the listed price is not the price I'm paying) leaves me some room to improve it as I see fit. It needs nothing, but as an initial matter I'm going to install some proper seatbelts. Also, since it'll be my daily driver, for fuel economy I'll probably also exchange out the dual Webers.
I pick it up on Friday--can't wait to drive it.
Thanks again. I'm very impressed with the 2002 community. Great bunch of people.
