I have a 06 plate with similar mileage to the one the OP is looking at.
It’s not bad, bit Tonka looking, AWD/4WD thingy helps in winter, tyres are about normal cost, VED is a lot but fuel consumption s OK for a big car.
servicing from near new is a PITA as it’s expensive.
so far we’ve had:
timing belt change@ £800
new flywheel @>£1k
various knocks and mumblings normally don’t expect any change out of £500 per service.
to my mind it’s expensive and wouldn’t get one again, but we’re going to keep hold of it until it dies properly, which at this rate may be about a year as it’s now developed a whining noise after the new timing belt.
we don’t kill cars, I have a 54 plate kangoo van that’s only had to have a new fuel pump. none of my cars previously have been such a hassle.
