I have a 1995 RRC Vogue (not SE). Coil sprung, cloth interior (no seat electronics), 300Tdi and R380 manual transmission, with no leaky sun roof. The electronics are limited to the alarm/immobiliser, SRS, and ABS/ETC (ETC on rear axle only). I have a plug-in module to bypass the alarm/immobiliser if that fails at an awkward time, but the other systems are not critical if they fail; the brakes will still work normally without the ABS and the SRS was an addition to the soft dash but nor a requirement.
It has done 190,000 miles and is still on its original entire transmission. The front diff pinion bearings have a little play and the CV joints and prop shaft UJs/rotoflex were replaced, but that's it. The BW viscous unit is still working perfectly.
The heater is excellent. I'll be adding AC from a 300Tdi DI, identical to the RRC Vogue SE's.
As a standard length RRC, rear leg room is a little limited when the front seats are all the way back (I need them back as I'm 6'), but load space is adequate. The LSE (LWB) has much more leg room for second row passengers, but at a lot more cost, parts replacement difficulty and at the cost of a lot of manoeuvrability.
As said previously, though, condition is the most important issue with buying any old vehicle, not age, mileage or spec.
