I'm looking at a E350 Drw 7.3 quigly conversation 4x4. I believe it to be a late 90's. It does have some rust. It's a former municipal vehicle. It runs and drives and has typical oils leaks associated with the diesel. Are there any particular issues with the frame or otherwise to look for with it? It had a short life as a bus but then quickly became a maintenance department vehicle the rest of its life. Thanks again. Looked with the search feature and didn't come up with much.
