My dad's been looking for a truck and we came across a really nice-looking, one-owner '08 Denali AWD, 6.2l for $9k. My only immediate concern is that it has 250k miles. Apparentyl is all original and mostly highway miles. Owner states has had it maintained regularly and has almost exclusively ran premium (91) fuel. Said everything works and not mechanical issues that he's aware of. I know to check for rust around the wheel arches and the undercarriage, door locks and windows that don't work, etc. I understand in '08 the 6.2 has VVT but not AFM, so that's a little reassuring. Just wondering if this is a good buy or not? He's going to use it as a second vehicle and probably will put 5k-8k miles/year on it. If it checks out, would you guys pop on it? The body and interior look really good, save for a small dent in the left front fender and a missing driver side running board. The passenger side looks to be power folding so that's a little weird, but certainly not a big concern.
