It's better to wait for one you feel good about, rather than to go out and buy something just because it's "there" and you're just dying to buy something.
Patience, man. I think it's super cool that you want something "old school".
Just be patient, and stay in the driver's seat- buy something that you'll love more in the future, instead of something that you'll regret getting into, and end up selling. A good buy, and intelligent ownership including "sweat equity" investment (i.e.- the work and cash you put into it) will only increase the value of an otherwise depreciating commodity- vehicles in general.
The trick here, is to have something which provides SOME level of transportation; and at the same time provides you with something you truly love owning. The real cool trick, is that the longer you own it, the more valuable it becomes.
Old school vehicles will definitely put a big grin on your face, but only if they're fun; by all means remember to keep the fun in it.
Good luck to you!
