Good advice, but I'd really caution you to buy it ONLY if you intend to mod or offroad it heavily. Even if the body, frame, etc. look good on visual inspection there's just no way to know what kind of internal damage might be there, or perhaps more importantly, if the safety systems still work as intended. For example, there's no way to know if the air bags will work until you actually need them. (And from personal experience, trust me you want them.) The starting salvage bid was $1300 and he now wants $4500 for it. That's only $3200 to repair and/or replace pretty much all the front body panels, trim, headlights, marker lights, turn signals, radiator, and bumper bar as well as repair the engine and/or other internals if they were damaged. What's the likelihood that he just bought a used dash sans air bags and installed that to save himself a nice chunk of change? Even if he replaced them, what are the odds that he used all new parts rather than used (and hopefully undetonated) air bags from another salvage VX?
If you intend this to be anything other than a weekend recreation vehicle I'd steer clear, even at that price. Just my $.02.
