I almost bought a local 309D a few months back, for a little more than the starting bid on this one - and it wasn't in nearly as good of shape. If I had the cash on hand, I'd consider bidding on this one (think about it - just needs the front end fixed and some paint!). The only issue is that you're looking at ~8 mpg on these beasts and they're not exactly quick. Good tow vehicles though.

(Oh, and I thought the brakes on those were usually air over hydraulic, not straight air... it makes a huge difference!)
