Thanks for your responses. I looked at it again today after seeing more pictures and the rust is definitely an issue that may be a deal breaker. Most is surface rust, but the penetrating rust is in more spots than I thought, plus the dirtiness of the undercarriage is making it hard to tell what is surface rust and what would need to be replaced, so I'll definitely have to be careful on that one. Spring seats and springs need to be replaced, as well as shocks. Luckily rust has stayed low on the car, hasn't gone to the doors, just on the body, and besides my welding friends need some projects to get better...haha. I'll look for slop in the steering as signs of wheel bearings gone, and listen and feel for some driveshaft slop.
Quick question, are there any common problems with engine problems such as blown heads, or thrown valves that I should be wary of for the future. These are easy to i.d. if the problem is happening now, but if its building up they become real expensive real fast. I know some engines are more apt to these problems, and I'm not certain what the specs are for the 6 cylinder. eg. aluminum head engines can start going bad at this mileage if driven hard. I like the idea of a diesel swap, maybe in the future if its a purchase for me. Something about people from Portland they always want to put a diesel in everything they see!
A buyers guide would be a great adittion to this already great site. Something to think about
. Thanks so much for your responses, I hope everyone is out wheeling this weekend or at least having fun in the woods. I'll post pictures when I take them.
