Those diesels were known to last for several million miles, if cared for. And if the body weren't rotted, you could be hit by a Greyhound bus and the bus would need a tow truck while you just putt-putted away.
By the way JP - you should check out the "Aviation Mystery Photo" thread for its Canadian connection.
