Where do you look to find cars for sale?

I posted a link a little while back to Valiant wagon on CL that was wrecked. I asked for suggestions on what yall thought it was worth. Got a few responses of 500-700. I took a shot and asked the guy if he would take $700 for it. No go unfortunately, said he wasn't ready to go below 1100.

Heres some pics. I'm really considering this, but am afraid I might be getting in a little over my head just because I am anxious to have something other than the XJ or the Camaro. It definitely wouldn't be a tinker while I drive car (at least not right away). Heres a few pics of it from his add.
