My personal opinion is that if a 4X4 is slightly out of market or like hard to find like this one, one should keep two things to decide about its market price. The first it's condition, and secondly your usage.
1984-86 TLC BJ74 are nice vehicles but because of their less availability, they are a bit expensive. Realistically speaking, if one has to go for a land cruiser and a 3500cc diesel engine, than it should be a 5 door vehicle. Otherwise if hardcore off roading is required (with a soft top), than there are other vehicles too fulfilling the requirement is less price.
