What to look for

I have found a running 1953 M-37. near my home. I'm going to look at it tomorrow. Is there anything special that I should be looking for. He is asking $2,800.00 it has a blue paint job. I was wondering about rust areas and such. any info would be great. I know nothing about these units.
Thanks,

Send pics asap, can make a better opinion.

On the rust issues. Look at the tool compartment that is under the bed of the truck near he front of the box, there will be a little door. Look under the headlights. If he does not have a top on it and you can fold the windshield down they also rust under the windshield where the windshield gaskit will trap water.

well took a look at it...and it needs alot. No rust but holes every where. It belonged to a fire department, then a logger, so it's beat up some in the bed area, runs some gauges have been changed to SW's, car seat, not really what I'm looking for....So with that said, still looking and single!!!
