My neighbour has been driving a ’55 for at least the 9 years Ive known him and he has a small holding: stock and feed trailers etc.
He rarely complains about it. Perhaps one electrical fault in that time. It keeps on going and doesnt look completely knackered either.
I cant really recommend a freelander – used to have one. The four-wheel drive system is awful. It uses a viscous coupling unit which only delivers drive to the rear axle after the silicone matrix has heated up enough to bind the drive input (Front axle linked) and rear output (i.e. after sufficient differential speeds/time between the two axles) which is usually far too late to be of use. Then over time the matrix degrades and permanently binds the two axles with no differential so you get rear axle drag and tramping on road which knackers the shaft mount bearings on the rear output shafts.
However, fitting good AT tyres and removing the coupling unit (which I did for the last few years I had it) actually turns it into an excellent two wheel drive “off roader”, but that still falls short of a proper 4×4. I cant say I know what kind of diff/4×4 system the Sportage users though.
EDIT: Sportage appears to have locking hubs which I think is probably a better solution as long as they dont seize.
“WARN vacuum-operated front wheel hubs, similar to Ford Explorer and Ranger. Rear corporate solid axle with a clutch-type limited slip differential.”
