I bought a 1981 International S1700 / Bluebird with MV404 gasoline engine, automatic transmission, power steering and air brakes sight-unseen for $250 -- knowing it was a gamble. When I went to fetch it, the carburetor flooded and a few other things seemed discouraging and I left it there. The main problem isn't the condition of the bus, but the foolish fact that I bought a vehicle sight-unseen 600 miles from my home! (Stupid, stupid....
The body is in great shape, but dirty. Tires are full of air, but basically junk. It built pressure for the brakes fine. The radiator is surprisingly clean inside -- tubes not clogged. Has nasty exhaust leak up front. 11 rows of seats -- bus is around 36 feet long. A couple of inches over 6' height in center isle.
I'll give it to you for $ 100 if you live in the Portland, Oregon, area and are a competent carburetor mechanic. Or have access to a big tow truck. Convince me that you have solid competence to move the bus from the sellers yard, and I will accept $ 100,- for the keys, bill-of-sale and title from seller to me, and a bill-of-sale from me to you. The bus is in the First Student yard on Hogan Road in Gresham.
I'll be looking for a hobby with a shorter commute!
