I think you're more likely to find a good vehicle on one of the enthusiast sites like this or ih8mud or the like. I watched CL for a month finding nothing, but there is good stuff there-just more crap to sort through.
Beyond that, expand your search-I bought a vehicle ~1200 miles away from me. Sure, it added a flight and some gas and some hotel stays on the way home, but if you build that into your costing you can shop anywhere in the country and adjust accordingly (there also is fairly affordable vehicle delivery these days).
Ultimately, you need to be quick. A good deal will go in under 24 hours-and if you didn't catch it you'll miss it. I messaged the seller within 2 hours of them posting, and had made an offer within 12 hours. I'd tried to get a couple others earlier but never was quick enough.
In a similar vein, I just sold my Civic on craigslist. I posted last night about 7pm, and I had a deposit in hand by 9pm. Finished the sale at 5 today. Had several other offers that came in after I had the deposit in hand (including one that was actually higher!) that I had to turn down because the first guy had been so quick to come out and put down a deposit. That ad is no longer visible-anyone who didn't look in a 22 hour period would never have seen it.
