300tdi engine then, there both very good engines with no really proplems,

if the chassis is mint and the rust is minimal then a good wax oil will do wonders, and its not expensive either.

Parts for them are buttons, check the landrover mags to see just how cheap they are. oil filters for about £4 etc

If it has sun roofs, watch as they can sometimes leak and that doesnt help the floorpan as it gets a bit rusty
