I just picked up a 2001 GMC Savanna 3500 "Shortie" 5-window bus. I found the bus on eBay and it was located in PA. I thought, "No problem, I'll just drive up and drive it back." I did and it turned into 12+ hours of driving. I live in the middle of Virginia and the bus was in the middle of Pennsylvania!
Anyway, I got a sweet deal on it. Only has a little over 82,000 miles and everything works as prescribed.
I got it to use for my construction business. I've definitely outgrown my E-150 van. I'll probably have questions about removing windows and installing sheet metal or installing safety screens over them (If I can find or make them).
Going to be a fun project!
