Not sure about $50 large worth, but it is cool.
ETA: I would love to take a K100, with the big double bunk sleeper, and an insurance write-off new model Paccar, and marry the drivetrain and axles from the write-off with the classic lines of the old body. An iShift Volvo would be easier to find, but that's like putting a 350/350 drivetrain in a '34 Ford. I know I'd probably end up at least at 50k, so I keep my hands in my pockets at the auctions.
