Jimny Gen3 what should I pay?

Sorry if this isn't the right place to post, I've been after a Jimny for about 10 years but keep wavering away due to some of the impracticalities involved in Jimny ownership. I have driven Jimny's of various ages abroad and do love them. I think I've finally settled that I'll have to own one sooner or later so why not now?

The problem is I have no idea what I should be paying, prices are all over the place from private sellers and seem to make little sense, I have seen 2007-2010 cars with similiar mileages listed at the same price as 2000-2004 cars with nothing in the advert suggesting why? Dealer prices are out of my budget unfortunately and I'd rather buy from a private seller who personally knows the history of the car anyway.

I'm not too bothered about age or mileage, post 2001 would probably be ideal for ULEZ. More important is condition, AC would be an absolute huge bonus as would the later VVT engine.
I'm buying in the UK and was hoping to pick one up for around £3000-3500 but the market seems to be a mess. Any pointers?

Look at the MOT history online.  Avoid anything with corrosion advisories.  I know some MOT testers are trigger-happy with advisories but this will sort the wheat from the chaff quickly.  VED liability is lower for pre-2001 cars but pre-2006 Jimnys are not generally ULEZ compliant, not necessarily because they're polluting but because they were built before Euro 4 existed.  At the cheaper end of the range, these things affect value.  But rust is the no.1 concern.

Also avoid anything that's been lathered in underseal
