92 Discovery TD good?bad?

I would go for a 95 or older if you have the money. They had major changes round that time and many problems were ironed out.

G'day Rich, if you're looking at getting the manual, be very wary - the earler ones had a few problems and at $14 000 for a new one its a bit steep.
the auto is OK. As has been said, anything after 95 has the newer 300tdi engine and the gearbox is a new unit that doesn't have the problems of the older one.
The main difference between the 200tdi (pre95) and the 300tdi is in the turbo and the use of a serpentine belt on the front instead of multiple v-belts. Performance is a bit better
with the 300tdi, but fuel consumption is about line-ball. As to how it stacks up against the hilux, it depends what you want ot use it for. The disco will be more comfortable on-road due to coils rather than leafs, and
if the hilux has independent front suspension, the disco will be better offroad too. If you need a ute occasionally the hilux it is, but for a comfortable wagon, go the disco. Cheers, Alex
