The long overhang on the D2 rear (it is longer overall, but has the same wheelbase so the rear overhang is a lot bigger) and the fact that both front and rear bumpers are one-piece, plastic, and splinter into a thousand bits at the first sight of a proper ditch, is bound to put people off - on the old ones the plastic end caps took a beating but were not that expensive to replace and could often be repaired. Also the caps and front skirt could be removed on a D1 making a fairly respectable approach angle, the only thing you can do to a D2 is saw the bottom half off and then it looks awful with the washer bottle hanging out the bottom etc.
The fact that the Td5 engine stalls as soon as it gets within 6 ft of a kerb probably doesn't help the appeal either, nor the fact that you really need to add an aftermarket centre difflock kit to make it work properly - the ETC by itself is rubbish on a D2, it always feels like it is struggling to control what is going on even in fairly mild situations. The fact it tends to panic and then throw a hissy fit when the going gets tough doesn't help either!
