And you haven't even mentioned the questionable engine & gearbox etc etc reliability of the newer models.
I don't live on the farm any more (it's only a couple of miles away though) so ours gets used as a skip, bike transporter, snow-trak, as a firm base when arrows get stuck on the roof (the joys of teaching archery to a 9-year old.
) as well as giving The Smalls something to practice driving off-road. My son (currently 11) has already claimed it as his 17th birthday present.
IMO, the early coil-sprung Defenders are the best compromise. It is actually useful on the road but still has the abilities and build of the earlier Series models.
That said, though, whilst I agrre that the current Defender has moved too far to the ground which the original Disco occupied, if you look at what they are selling, many / most Defenders seem to be safaris which are family cars, rather than the work-horse you describe. Our farm trucks are now Ford crew-cabs, with leccy windows, air con, relatively decent ICE and they are proving just as good long-term as the 88"s were.
I think that the most telling market, the long-range travellers who head off to spend years in Africa, for instance, and need reliability and ease-of-bodging are either using older Defenders or, for those with the cash to buy new, are looking at stuff from Mitsubishi or Toyota.
Much as I love the RR and Disco III (there, I've said it!) they are just as aspirational now as the metal from Merc & BMW, utility is not the market that they seem to want to occupy. Which is a shame.
As for going off-topic... "they all do that, sir!"
