90-110-Series superb off road and short journey, not great on road etc, but cheap parts and easy to fix.
300tdi Disco is more comfortable and again will go pretty well anywhere cheap parts, but do rust underneath.
Freelander TD4 is the best, especially the commercial, very good engine, but nowhere near as good as a 90 or disco off road, Ok but not great.
I have had all 3 of these and prefer the disco.
Jap stuff can be good but parts are expensive.
