I think the biggest single feature you have to look for, with high-range, high-tech used vehicles, is how many are for sale just out of the warranty period.
Range Rovers seem to feature largely in this group. Of course, it may be that the demographics of most new Range Rover owners is that they turn over their vehicles very regularly, and they do so, because they can afford to.
Most Range Rovers, as we all know, rarely get off the blacktop. They are loved by the Toorak Taxi set, by the wealthy mothers who need a status symbol to run the kids to school.
Having said that, that does usually make for a wider choice of better-condition vehicles when looking for a used one - and it does seem there are plenty to choose from.
The 2.7L V6 diesel engine is a joint Ford-PSA product that is particularly high tech, in the best European fashion. The engine is produced in many factories around the world, and fitted to a wide range of vehicles. Many specific engine components of the 2.7 are built in Ford South African factories and then shipped to other global factories for final assembly. Here's the main users of that engine.
2004 Jaguar S-Type
2005 Land Rover Discovery
2005 Land Rover Range Rover Sport
2005 Peugeot 607
2005 Peugeot 407 Coupe
2006 Peugeot 407
2006 Jaguar XJ
2006 Citroen C6
2007 Jaguar XF
2008 Citroen C5
2011 Ford Territory
Note that each vehicle uses a specifically-modified engine for the application. The Range Rover engine has specific variations in design over the other 2.7 engine users, typically such as a larger sump.
There are reports of a number of problems with the 2.7 engine. Most appear to be related to oil issues. The originally recommended service interval of 24,000kms appears to be too long to me, and is probably behind some of the engine failures. My personal opinion is that no diesel, particularly a high-tech one, should have engine oil changes this far apart.
The 2.7 engine uses bearings that have no locating tabs. The bearing
shell is merely clamped by the conrod bolts. This smacks of cheapness in design, because bearing
shell tabs have been an integral part of engine design for over 80 years.
This tabless design leads to bearing shells spinning inside the cap when lubrication becomes less-than-perfect.
This is typical of high-tech engines, they are called high-maintenance engines, because they are finicky with their required operating parameters. Let the oil get dirty and thick, and they will fail, because they can't cope with it.
Low-maintenance engines have much wider parameters of operation, they can cope with all types of poor maintenance and poor operating conditions.
The other problem areas with the 2.7 engine is in the variable vane turbocharger. The variable vane turbocharger is a very high-tech device that performs better with an increased ability to change to varying operating conditions, than a bog-standard, fixed vane turbocharger.
However, the finicky little moving components that operate the movement of the vane angle become clogged with carbon and other combustion deposits after around 100-150,000kms and then they start to fail.
Naturally, they then need to be replaced at high cost.
The 2.7 engine needs a range of special
tools to repair it, such as the Ford timing tool.
Camshafts and crankshafts have been known to fracture, due to the high-tech, lightweight design, where weight was pared from the engine to produce a low engine operating weight (202kg) that was low enough to ensure that it could be fitted to many smallish sedans.
Other problems reported with the 2.7 engine are EGR problems (common with many newer high-tech engines, and also related to carbon buildup causing clogging of the EGR operation), particulate filters that cost a fortune to replace, injector and glow plugs failures, and intercooler failures.
Range Rover design is such that to remove the engine totally, for major repairs, requires removal of the body.
The following websites provide some insight into the 2.7 engines, where owners, repairers and potential owners discuss problems associated with the engine.

The South Africans have had some 2.7 engine problems that appear to be maintenance and oil related. Once again, high-tech engines don't do
well in harsh conditions and where maintenance is lax.

The Range Rover is a particularly comfortable vehicle that offers a "driving experience" that appeals to a certain demographic of people. There is also the status angle of driving a Range Rover that appeals to numbers of people.
However, buying a used high-tech vehicle such as the vehicle you're looking at, requires careful scrutiny of the level of maintenance and the style of use that it has endured.
It's highly likely you will find a very nice example, that has been
well-maintained and only lightly used.
Against that is the knowledge that you must always keep in mind, that these vehicles are complex, high-tech, and very expensive to repair once they get high kms on them - and if you have no warranty to cover any unforeseen failures - be they mechanical or electrical - then you will be facing some heavy slugs to the wallet, when they happen.
Good luck with your search - a vehicle choice is a personal one, and one that we make according to our personal needs and requirements, and very often, how we wish to project our image.
Cheers, Ron.

The service interval on these engines is 12,000km not 24,000km. Certainly the vehicle is no more expensive or complex to maintain than on comparable 4wds such as the 200 series and high end Prados and Pajeros.
Most work including engine changes can be done with the body on but it does need to be understood that from the design stage the vehicle was designed to have the body off for particular work - as such it is designed to come off with the majority of fittings simply unclipping. Once set up - all is needed is a hoist - it is less than two hours to lift the body - it just unbolts and unclips.
Yes - like all modern engine - oil selection is crucial but it is easily obtainable form
places like Repco, Supercheap etc.

I'm looking at the Ford tech drawing (explosion diagram) for the 2.7 "Lion" TDCI engine and the bearings look to have locator tabs on them. A bit hard to tell from the resolution of the image but there is something on the bearing
shell in the shape and location where you'd expect a location tab to be.

Closer inspection of the said tech drawing indicates the marks are oil channels, not tabs.

The problem mentioned does exist but is exceptionally rare and only applies to early 2.7s. Later 2.7s including those in the Territory do not have the issue.
