I used to drive an older Range Rover... I loved the truck, but I would never buy one again. First off, compared to anything US or Japanese built, they are drastically underpowered. My Rangie had good torque and towing capacity, but was slow as poo. It was also a gas guzzling whore! I was getting 12 miles per gallon on good days and without running the A/C (a feat in central Florida) and you need to use premium fuel in them. So gas gets really expensive in them. Also insurance is rediculously high and for no real reason in them. I was paying about $125 a month for mine with it listed as a secondary vehicle. I now only have one car, a Honda Accord (most stolen car in US) and I now only pay $41 a month. HUGE difference. Oh, and the $125 was just for my Rangie...not for 2 cars.
If you do buy one, I hope there is either a dealer near you, or a specialty shop you trust. For me, the nearest dealership was 80 miles away in Jacksonville. Breakdowns aren't as bad as some people make them out, but it's not breakdowns you need to worry about...it's all the other little things that will go wrong that you just learn to live with. For example I couldn't roll my windows down from the center consule, but only from the switches on the doors for the rear windows, but vice versa for the front. Weird things like that. All Rover vehicles have bad problems with heater cores failing, so since you are in Alaska, you will have some issues there. I would tell you if you get one to have the entire radiator and heater elements and A/C replaced at an aftermarket custom shop as soon as you get the chance. Also, make sure you buy a Rover with coil over shocks. The air-ride suspension is great when it works, but when it fails, don't spend the money to fix it. Just replace it with Bilsteins and Rover Tyme springs. You will have a better ride for half the price.
Those are just some of the more common things to look out for, but if I were you (and remember, I have been down this road) I would tell you to get something domestic or Japanese instead. If you want a daily driver, don't go Rover. If you want the best off road truck you can buy and you don't mind basically stripping yours and modifying it to an off road truck, they are fine, but if that's the case buy a used pre-95 Rangie SWB with the 4.2L in it. Replace the suspension with coil overs and have it entirely rewired and have a custom radiator installed.... all that would probably be less than a newer Disco and be a better truck anyways.
Like I said, I loved my truck when I had it, but I wouldn't buy another one anytime soon.
