The Land Rover Discovery to lean towards is a 2017-on 2.0 diesel with its oil changes and air suspension checked, because the 2.7 and 3.0 V6 diesels each carry a known fault that wrecks engines.
5 known faults, 4 rated high severity in our database; owners report 30.6 mpg, 81% of the official figure. Everything below is built from that data and the archived owner history, not from a press car.

It isn't a clean bill of health, though. A 2017 service notice said the 2.0 and 3.0 V6 diesels were getting diesel in their oil from too many filter regenerations, and the High air suspension fault covers every Discovery from 2002 to 2020, so the suspension checks below matter on this one too.
Be very wary of a V6 diesel. The 3.0 of 2009 to 2017 carries a High known fault where a crankshaft bearing spins and snaps the crank, seizing the engine, often without a warning light first. It's listed at 19,000 to 75,000 miles, and Discovery 4 owners reported it at 55,000 and 59,400 miles. The 2.7 of 2004 to 2009 has its own High fault: the belt tensioner hangs off the oil pump casing, and when either lets go the engine's finished.
Don't take a later Discovery 4 as the fixed one. A 2014 service bulletin covered 2009 to 2012 3.0 diesels and suggested the design changed in 2012, yet the known fault runs to 2017, and two 2015 cars failed at just 19,000 and 22,000 miles. A 2018 Discovery 5 V6 diesel needed a new engine too. On the Discovery 3 (2004 to 2009), the electric handbrake jammed or failed on more than one car.
The Series 2 (1998 to 2004) is a different buy altogether. Its High known fault is the rear chassis rails rotting from the inside around and above the fuel tank and at the rear crossmember, where you can't see it without getting underneath. Cars from 2002 on also fall under the air suspension fault, so there's no era of Discovery that's free of a serious known problem.
No Discovery engine is a safe bet, but the 2017-on 2.0 diesel is the lesser risk: the crankshaft fault doesn't name it and what's on record against it is milder. It's got decent pace for such a heavy car, but it's part of the 2017 notice about diesel diluting the oil, 2016 to 2018 2.0 diesels were recalled because CO2 output could exceed the limits, and one 47,000-mile 2017 car (the report doesn't say which engine) had its turbo and crankshaft replaced while chasing a stalling fault.
The 3.0 V6 diesel of 2009 to 2017 carries the High crankshaft fault, and one owner paid more than £16,000 for a replacement engine on a 2011 Discovery 4 at 55,000 miles. The 2.7 has a High fault of its own, covered below, so neither V6 is the safe pick. On the 3.0, the body has to come off the chassis to reach the twin turbos, so any turbo work there is a big job. Its timing belt is due every 112,000 miles or 7 years, whichever comes first.
On a 2.7 diesel, several owners lost engines when the timing belt tensioner failed or the oil pump casing carrying it sheared off, including a 2006 car at 88,000 miles. It's a High known fault, listed at 60,000 to 88,000 miles. One owner of a 2007 car was told the oil pump must be upgraded whenever the belts are changed. The Discovery 3's Jaguar V8 petrol isn't named by any known fault, but there's little on record for it beyond recalls for fuel leaks on early petrol cars.
Discovery 3 manuals have drivetrain trouble on record: dual-mass flywheels and clutches giving up on young, low-mileage cars, and one owner needed two clutches and two flywheels in three years. Early Discovery 3 automatics were recalled because the Park function could fail to work. One owner's automatic failed at 115,000 miles, and the owner was told by specialists that the fluid needs changing far sooner than the schedule's 150,000 miles or 10 years.
Air suspension comes first, since it's a High known fault on every car from 2002 to 2020, showing up between 60,000 and 120,000 miles. Look for a 'Suspension Fault' warning, a car sitting lower on one corner or down on its bump stops, and a compressor humming away at the rear without stopping. Raise and lower it through its heights and check it levels out. One owner damaged the compressor after mistaking its mounting for a jacking point, so ask how it's been lifted.
On a 3.0 V6 diesel, listen hard for any loud knock from low down in the engine, as the crankshaft failure often gives no warning light first. On a 2.7, a rumble from underneath and a loss of power are the signs, so ask for the invoice showing the belt tensioner was renewed and the oil pump upgraded. On a 2017-on diesel, the history should show oil changes at regular intervals, not stretched ones.
Work the electric handbrake on and off several times and make sure it releases cleanly; one owner of a 190,000-mile 2005 car spent more than £3,000 on it and it still jammed. Listen for squealing or sticking rear brakes, as the rear back plates corroded early on the Discovery 3. Check the front lower arm bushes for play, as they wear on both the Discovery 3 and 4, and one owner paid £800 for new front wishbones at 27,000 miles.
Get underneath. On a Series 2, tap the rear chassis rails near the fuel tank and rear crossmember and listen for a hollow sound, and look for flaking, holes or welded plates. On later cars, check the removable towbar isn't seized or its mounting rotten, and that the underslung spare's still there: thefts are reported on the Discovery 3, 4 and 5, and one owner paid £1000 twice to replace it. Ask for proof of the seatbelt buckle, Park function and fuel leak recalls on an early Discovery 3.

Land Rover Discovery Real MPG by engine →It's a properly capable off-roader that still drives well on the road, handling far better than something this big and tall has any right to. The Discovery 4 blends pace with refinement, and the Jaguar V8 petrol in the Discovery 3 is much quicker than the diesel. That size and weight also make it a strong car for towing a caravan or trailer.
The 2017-on Discovery is very comfortable, and that's what makes it such an easy car for long trips, where it'll cover big distances without wearing you out. The Discovery 3 looks stylish and it's still a capable thing off the road, while the 2.0 diesel in the newer car pulls well for something this big.
