i have a ex-mil landrover 110, in 6yrs i have only had a few issues, clutch exploded requiring a strip of the transfer box-gearbox assembly and a annoying electrical problem that left me without tail lights in mid winter( quickly worked out i could make it the 20 miles home using the the rear fogs as rear lights, slightly illegal but didn't seem to get noticed by other motorist who probably thought i was on manoeuvres :wink:)
it's been parked up since christmas but my wife moved it a few weeks back and it started first turn of the key.
apart from that, cant think of anything else, i am going to buy another more modern 110 defender as soon as i get the cash,
hired a terrano for 2 weeks in cyprus this year and that was pretty good if a bit flimsy, wouldn't buy one myself but worth a look,
used a disco 300tdi for 3 yrs towing ski boats, good workhorse fairly fast and comfortable but from new it had 3 gearboxes, two transmissions and several turbo's, make your own opinion on that one.
