I've had three discos and a freeloader, all diesels. The Freelander (S reg bought new) was the most reliable and drove more like a car. Took it off road in Turkey, and Romania (actually Romania didn't
have roads in those days). But it wasn't big enough for me and I missed the bottom box and the ground clearance was rubbish (bent the sills and snapped the stay on the under-engine "protector" doing a rescue on Dartmoor). The three discos have all cost me far more to maintain, but fit my needs better and are lovely to drive
when they are working. Best of the three is the TD5. I don't think I'd go back to a TDi, especially the 200 - a bit agriculturrral ooo arrrr...
Whatever you get, keep some of that cash for repairs.
