Hey there, I'm looking at a 96 f250. It has 240k with ts 6 position chip with tony wildman tunes. it is 4x4 as well. 4'' exhaust too. It is a 5 speed with a new 350 hp clutch. I dont know much about diesels as I have never owned one yet. Any tips on what to look for? How much should I pay for it? What will it get for MPGs?
