I use a similar method to search nationwide on Craigslist (which Craigslist itself doesn't let you do). I enter the following into the Google search window:
"Dodge school bus" site:craigslist.org
Put whatever you want, e.g., "Thomas Saf-T-Liner," in place of "Dodge school bus." Use quotes and don't put a space between the colon and "craigslist.org." I've seen buses for sale as far away as Fairbanks, Alaska. If I don't use the quotes, the results will be craigslist listings that include a 2010 Dodge Challenger mixed in with someone's "Magic School Bus" VHS tape collection.
Do follow precautions against avoiding scams; I doubt that honest craigslist sellers will deal with someone they can't meet face-2-face. But it did get me as close as I've ever gotten to a bus I could buy: a good one in Iowa that I probably would have missed otherwise. Darn shame the owner couldn't meet my price. Patience is a virtue.
