The Russians do build some tough, durable and reliable things in spite of what some people think.
The info on the range rovers I get is from all the car salesmen I know. They won't even take them in on trade ins because when people bring them in the range rovers usually require a few grand in repairs just for minor things like broken lights or non working instruments on the dashboard. The parts are very expensive. Also I have been told that they are prone to electrical problems that are a pain to fix. Now I am talking about the newer ones and I see the ones you have owned are older.
In regards to old soviet vehicles I would like to have a LuAZ 969M or a GAZ 69. They are both simple and you can pick them up pretty cheap.
