Bought two busses from Craigslist, and paid $1000 for each.
First one ran but not properly and after a few weeks of working on it i threw in the towell and out it back on craigslist. The guy who sold it to me bought it back for the same price
This one i drove home and after a serious tune up she runs perfect.
I have been watching bus prices for some time and it seems most people here spend under $5k.
