Price is a little high, mileage isn't bad, but for you big question problems... it doesn't matter what year the Land Rover is, it matter more if it has been taken care of. Your average 1st owner of a Land Rover will not maintain it they way is should be taken care of, the 2nd owner is normally worse, then we buy them and they need lost of TLC to make them happy again.
Without seeing the Rover, driving it and looking under it, even checking the fluids I would be hard pressed to give advise on my Rovers.
I helped a friend the other day change fluids in his 2 RR's one of them I don't thing the U-joints have ever been greased and when we changed the Diff Oil it came out like grease, not oil. Externally it looks great, but it hadn't been taken care of.
What I am say is unless you are mechanically inclined either take it and pay someone to look it over, or be prepared to spend about $500 - $1000 getting everything back up to where it should be if it hasn't been taken care of.
I also wouldn't go more than 10k with tax and tags out the door.
