Would I be correct in assuming the se7 is a tdi so you are comparing diesels?

The tdi is slower, especially if its an automatic, but it is far simpler. It will definetely have coil springs, the auto is a hydraullically controlled ZF (as opposed to electronically controlled on the D2), the manaul and transfer are the same on both, R380, and LT230.

The LT230 is a very strong transfer case, probably the best thing LR have made. They are still in use today in Defenders. The D1 will defienetly have the Centre diff lock, this was removed in some D2's Depending on the year they will either have, the mechanism but no lever, nothing atall, or it all replaced. Some D1's would have had the input gear which had no oil feed holes, and this wore the main shaft splines and input gear splines prematurely. On an Auto this is an easy fix as the back section of the shaft unbolts, but on a manual it requires more work (main shaft replacement in gearbox)

The r380 gearbox has undergone a few changes over the years and the D2 one (and Defender td5) is the best of them at what they term suffix L. The suffix K is very similar but the D1 will likely have the Suffix J, which while not bad, did suffer from occasional broken layshaft issues. This was improved and apparently designed out in the Suffix K but I did manage to break a Suffix L one!

The D1, with the 300tdi, will be mechanically fuel injected as opposed to the TD5 which uses Electrically controlled unit Injectors. They are both very good on fuel. I prefer the TD5 over the tdi but that is just me. I have done a lot of work on the 5 but only limited stuff on the tdi. (through choice)

Suspension. The D1 uses Radius arms and a panhard at the front, and trailing arms and a frame on the rear. These work very well. The D2 uses radius arms and panhard at the front (but with pivot bolts at the chassis end as opposed to the pin through bushes of the Defender and D1) but at the rear uses radius arms and watts linkage.

Watts Linkage is very good for road holding but does limit the rear travel slightly. The rear suspension on the D2 may also be air bags. These can leak. If they do start leaking replace them with new ones or you will be buying a new compressor too and they are expensive. If it is a 7 seater D2, it will be air sprung on the rear. (if its a factory 7 seater and has rear coils someone has swapped them as they were only approved as air sprung for the 7 seater)

The rear seats in the 7 seat D2 are far better than in the D1.

The D2 is a far more complex vehicle overall. It has a BCU, traction control, ABS (as do some D1's), Hill descent control etc etc. The abs/traction/hdc is known to generate a few issues on the D2 which is commonly refered to as the 3 amigoes.

Parts in general are no more expensive than toyota or Nissan ones. In some cases they may well be cheaper, especially if you order out of the UK. Normally parts arrive within a week.

With D2's there are several diagnostic tools available so you can play about with all the electronics yourself. on AULRO there is acutally a map of people all over Australia with them who are happy to help others too.

There is heaps of other stuff I could write but thats a start! let me know if you have any specific questions

one last thing, if you want to make it a serious off roader, the D1 is a better base as its smaller, and has a lot more interchangability underneath with Range Rover classics and Defenders, but the D2 is a far better car for long distance stuff.

Just make sure if you get a D2 that it has the centre diff lock fitted, otherwise walk away.

Here and there
