To add to the above, we’re on our second but only as we had to move the first one because it was manual & swmbo needed to get an auto due to a knee injury. Very reliable car, especially for a Land Rover!
Cam belt replacement was 10 years (or equivalent mileage) for earlier cars but then reduced to 7 years for later ones - don’t ask me why, it’s the same engine & belt! Check it’s been done & higher mileage cars may have required a second replacement by now.
When we got the auto, a 2013 SD4 HSE approved used from a main dealer, we had a water leak into the boot, dealer tried several times to find it but failed. Eventually tracked it down to the seal around the third brake light at the top of the tailgate. Seals not available from LR so it required a new light unit at their expense!
Service history as above & check MOT history to see if there is any indication of poor preventative work or generally not bothering with stuff till it’s broken or has to be replaced, eg damaged or worn tyres, worn brakes, etc coming up regularly. Also look at tyres, are they matching or Heinz 57? are they premium or budget, are they worn evenly?
While on tyres our first FL2 was on 17” rims & tyres lasted forever. The SD4 came on 19” rims & chewed through tyres like they were going out of fashion - sidewalks not deep enough. Swapped onto a set of 17” rims & problem solved!
Had to replace a radiator on the first one as it started to weep - can’t remember the details but it turns out it’s from a Volvo so no need to pay for genuine LR parts there…
Low tone horn failed on the SD4 & it’s a pain to replace as you have to remove he whole front bumper assembly. While it’s off, assuming you have hem, check the wiring for he front parking sensors as it can & does wear through if not clipped in properly.
+1 for the FREEL2 forum, lots of useful stuff & people on there.
Would I have another one? - yes, definitely.
