Regarding the comments on the gearboxes, there was a problem with the early 300tdi's ('94+) but I don't think it effected the 200tdi's ('94-) where there was not enough oil getting into the transfer and the mainshaft splines would wear prematurely.
A sure sign of this gearbox problem was a clunk from the gearbox when you accelerated.
I believe this problem was rectified by LandRover themselves in '96 but most of the 300tdi's pre-96 have either been fixed or never had the issue in the first place.
