1st piece of advice, DON"T buy anything in the Pittsburgh area or anywhere within 750 miles of Pittsburgh. Rust will be a major issue. I think this is one of the most important variables in buying a bus, the amount of rust. There are too many areas west of us that have rust free buses for the same price as the rusty north ones. The worst rust on a bus is often hidden under the floor and can't be seen until you remove the floor. Really nice exterior looking buses have cancer through the floor that isn't visible, so the trick is to just stay away from the NE area. The west doesn't use salt on the roads in winter, salt is what rots the buses.
