Spent 3 days offroading in the Malaysian jungle in a convoy of Defenders (old, beat-up, heavily customised ones). Best trip ever. Crossing ravines on bridges made of nothing other than 3 tree trunks, fording rivers, climbing up ridiculous inclines over boulders and camping out under the stars (in mozzie nets...). There was also a fair amount of drinking, but that didn't seem to affect the driving much. If they broke down (which they did), the one of the amazingly competent mechanics would fiddle with bits, whack some other bits, and they'd always come back to life. (On a previous trip they'd broken a driveshaft, so went back to an abandoned Land Rover they'd come across a couple of miles back, stripped the driveshaft from there and put it on their one!).
Also we took a trip to the Cameron Highlands. That place is literally full of old (S1 and S2) Land Rovers. There is not a new car in sight. They just keep them patched up and they go on forever. They're used on the tea plantations.
Luckily a good friend of mine runs the owner's club in Malaysia (and helps organise the Rainforest Challenge). Good place to go if you are a LR geek!
