Man, you guys are pretty cynical about this! It's hard to say if it's worth it without seeing and driving it, but I also wouldn't say 200,000 on the stock engine is a bad thing. I have over 340,000 on mine, and it's rusted stuck a couple of times(cylinders looked like they'd been sandblasted!), doesn't smoke yet either. If you can verify the engine in the bed is a good engine that sweetens the deal too, but that could be a tall order. If the paint is good and the interior is "new", he potentially dumped more than that in it. It really boils down to what you want it for; are you gonna wheel it hard and bash it off the rocks? or are you gonna DD it and occasionally do easier trails and not rub it on the rocks or trees? If it's in really good shape I'd offer him maybe $2500 and do the latter option, but if you wanna wheel it hard hold out for one with a shitty body and build it right, and for a lot less.
Do you have a preferance in year? If not I just picked up an 86 fourby and might be willing to part with it for a lot less than he wants, and I probably could come up with a straight axle for ya too. The body is in a lot better trail shape too, so you wouldn't hafta worry about rubbin it on the trails. Is Medford pretty close to springfield? I never remember if that's medford or grants pass that's close. Nate
