The Disco 2 is not a rebodied RRC, even basically. The Disco 1 is.
The Disco 2 is a completely new car, admittedly of "similar" design, and very similar styling. It was produced only for a relatively short time and shares few parts with any other model, including its successor, leaving it as a potential orphan. It has very complex systems (like most modern cars) which make it wide likely to suffer complex (i.e. expensive) problems. Same situation as a P38, but mollified a bit because far more of them were sold.
Part of the general syndrome with luxury cars - those who can afford to maintain them, can afford to buy new, and usually do. So this makes them very cheap by the time they get out of warranty, and especially once they reach ten years or more in age.
This tends not to apply so much to Defenders and RRCs, as these both had very long production runs and were/are a lot easier (cheaper) to maintain.
I have recently got a Disco 2 TD5 for my son, at what I consider a reasonable price (as with any purchase of a S/H car, "reasonable" depends on condition. I would actually have preferred a D1 for the reasons given above, but I was unable to find a suitable one, and this one was too good to miss. Unlike some of the other ones I looked at!
