I'm gonna have to try to encourage you to go with the newer one for many reasons.... parts is one, safety , maintainance, and its not what you want. If ya want the Diesel, go for it , they work great for what you need it for. That old bus will need a lot of parts replaced just to make it roadworthy. I'm sure, brake lines, wheels, tires and engine work, the list could be endless and expensive. Old bus engines in prime working order have no power, Old bus brakes in prime working order have no power...Old bus bodies have lots of places to hide rot and rust, Old bus Radiators are hard to find in decent shape.. if this old bus isn't in prime shape you'd best walk on by. The thousand ya save will be eaten up pretty quickly and you still won't have what you want.
