I live in Spain and purposely bought a Disco 1 for it's simplicity. Out here you can drive for 20 minutes out to the campo and park for a weekend and not see another soul! With this old girl you throw away the battery, alternator, starter undo the fuel stop and with a quick push off it will go. Try and do that with Jap machine that relies on half of the computing power of a nuclear sub just to start up!
I tell no lies you will have to 'fettle' it every now and then but it depends on your way of thinking, if you do not mind topping up the transfer box once every three months or so and greasing the props whilst your under there then get a Disco.
Less is more when it's the difference in getting home or not, mine starts everyday without fail, will sit on the motorway at 120 kph for two or three hours and then find itself halfway up a mountain in thick snow. 45 minutes later it will be on the beach (and I mean 'on the beach').
I love it to death and incidently as its quite old it has to be MOT'd every SIX months and has yet to fail!
