I miss my Landies - a 109 and two 110s over the years. All "Station Wagons" mind, so a little more refined. I learned a lot about working on vehicles thanks to them - - - and I note that my tools seldom get taken out and played with these days. Now, why is that I wonder?
If you can't work on them, stay well clear. On the other hand, once you've been bitten by the bug, there is, I'm afraid, no real cure. There is however a very big difference between an exMoD 90 (perhaps soft-top) and something like a 90 Station Wagon, preferably the pukka version not the home brew variety.
All of mine leaked, rattled and burnt / leaked oil at an alarming rate from places you've never heard of and can't find. I spent many happy hours keeping them looked after and each one was suffering some serious rust in places they shouldn't rust after a surprisingly few years. We towed big trailers loaded with masses of camping kit (I was in the Scout Movement at the time), with the vehicle full of people and the roof-rack also fully loaded. And the kids absolutely loved them. They also got off-roaded either just for fun, green laning and the occasional competition.
Which reminds me - add the ability to weld as another essential skill if you plan on running an old LR. Oh, and you really do need a driveway or similar - working on one in the road isn't nice.
None of mine were my daily drive - as I had a company car at the time. My then wife used them as daily drives, but of course whenever the Landy was off the road for whatever reason we had another means of transport. All this said, only one of them every actually "broke down" - and that was a perished water hose which really should have been changed anyway.
I still want another, although these days I can't justify one either for the fun of it or as a long distance vehicle, which is what I need these days.
