That truck has secrets , I'd be sure to bring old clothes a good flashlight and take my time crawling all over/under it and really look up under the dash for that hidden rust .It's been sitting in that same spot for a long time just by looking at the tires in the dirt , From these pictures I'd wave $2,000 in cash in front of him . Also I'd want to see it on flat pavement to see if it's twisted or just looks that way in these pics ,$3,500 still buys a lot of decent trucks ....
It's easier to flip a $10,000 truck for $15,000 than it is a $2,000 truck for $5,000
