Well, I'll take a shot. I do see what appear to be a few dents, scratches, and a little rust in the pics, but it is pretty clean for a 97. Blue book value for a 97 E350 in excellent shape is around $3200, with private party sale around $2600. That and the truckmount is a 33 blower based unit without catalytic converter or exhaust diverter, and I would not pay more than about $5K. If you're in love with it and must have, maybe $6K. But that's just me.
