But you did have a very early petrol model Lambert, and they are thirsty.
The TDi models (look for bonnet scoop for intercooler) give much better MPG and run happily on Bio - I use 100% at this time of year and 75% during the winter. Similar performance to a disco TD5 for way less money.
As you say they are seriously cheap at the moment.
The only real differences between Maverick and Terrano are bits of trim and the badges. All were assembled by Nissan in Spain and use the same running gear. You will come across Mistrals too which are Grey import Jap built ones, better trim levels still etc but higher prices.
Look for rusty cills especially on SWB models. Rusty seat belt mount points (in rear arches), early models had weaker gearbox so listen for noise if buying an early one. TBH theres not a lot else, in a good few years of ownership I have replaces, 1 starter and alternator (done a lot of wading though) and a steering idler at about £20. Other than that its been service items or modifications. Sure parts are a bit more than landrover parts but you don't need them that often and there is a good market in 2nd hand bits.
