Welcome to the forum. Having just looked at the pictures for the grey 80 on ebay, has it had a light front end bump? The front panel (panel with the front indicators) is out of line with both wings; bonnet to wings gaps look okay. Is the condensation due to the carpets being wet vac'd by the dealer, or does it have water ingress? Water can get in round a badly fitted windscreen, check the front footwell carpets for damp; also there have been reports of the rear quarters corroding from the inside out from condensation between the inner trim and the rear quarter, or from water getting past the sliding rear window seals, plus the drain points are often blocked. Worth having a look and feel in there on any potential purchase, as rust can take hold out of sight in the wheel arch and behind the rear bumper.
Also check that the difflocks work, the axles lockers flash on the dash once selected and then the light goes solid once engaged, if they don't work haggle money off, as they're not a cheap fix. Lots of info and advice on here, so have a search and you'll be all clued up to find a gem.
