I have one of these "soft dash" models, though I specifically went shopping for a Vogue rather than a Vogue SE in order to avoid the leather, electrically operated seats (prone to ECU problems), air suspension (an expensive nightmare) and the ubiquitous leaking sunroof.
Mine has a 300Tdi engine, R380 and Borg Warner transmission (viscous coupling and chain drive, far superior to the LT230) and coil springs. It's a lovely vehicle, though the leg room is disappointing in both rows. It's still comfortable, swift, easy to drive and immensely stylish, even though its lines hardly changed since the 1967 Velar prototypes were built.
If its chassis and body are good, then go for it. But be wary of all those electrical faults. You could just disconnect the SRS units and pull the fuse, removing the light bulb from the dash as a cheap remedy - the hard dash RRs never had SRS anyway, and the Discovery only had it on the drivers side, not both like these soft dash RRs, so they can't be that essential.
Have a good look at the boot floor, under the sound proofing, the foot wells, sills, front inner wings/wheel arches, and if the owner will permit you, remove the indicator/sidelight units (just two screws each) to check the condition of the steel behind them - those are the usual trouble areas.
