Kiker, with that many miles and 8 years, it should show what kind of care it has had. Has the transmission been redone/serviced, GOOD ball joints, steering box dry, stock air filter box with decently clean filter, paint ok or baked out from Texas sun (sheltered?), interior presentable, radiator clean inside and out, oil changed on schedule and good filter. ? How is the A/C and heater doors? Rear end quiet? Oversized or mismatched tires? Has it had any injector work and by who and with what parts? Shocks? How does it drive? Does it just feel like it sits in the road good? The Cummins start good hot and cold? Any programmers or mods except MAYBE a Smarty Jr would turn me off. My buddy Chris has an 03 with 280k and he wouldn't take $13,200 for a down payment for his. There is an 05-06 here with around 140k not worth $2500. Is your son old enough to realize it isn't a new truck and that he would need to operate it with "an ear to the ground"? If the truck can sell itself and not hurt itself, I would think that it is worth the price. Mark
