If your thinking about doing this you need to educate yourself on the difference between a Disco1 and Disco2. Those trucks are so different that it's like talking about 2 different trucks. Like Ford and Chevy literally. I personally think you should be looking at a Disco1. Unless your a big fan of pain and suffering.
BMW fucked up a perfectly good truck when they built the Disco2. You can't keep coolant in them, Most of them don't have a center diff lock. They usually end up with the three amigos (abs ,traction control,hill disent control) because of shuttle valve problems in the brake modulator. The wheel bearings on a Disco2 are like the ones on your grampa"s Buick instead of a semi floating axle bearing assembly like you get in a Disco1. Semi floating axles are what you see when you move into 2500 series trucks with GM. Think bigger stronger. Disco1 has a military swivel ball setup instead of plastic CV boots.
You should look on all the car sites in the west for a solid rust free unit and think about having it shipped home. I paid a grand to have one shipped from Norther Cal. to Chicago a couple years ago. You should be able to find a really nice truck for 4 grand. If your going to pay 6 grand it better be a really nice truck. Somebodies selling a willow green 96 with a standard trans in the vehicles for sale section. That truck is worth what hes asking from looking at the pictures. If I was looking for a truck I would be all over that thing. It's got a lot going for it to raise it's value over the rest of them. It's a rare and desirable color and it's a manual trans truck. And I don't know the guy selling it, so I don't have a horse in that race.
