I thought id post my success story, seeing as these cars tend to get a lot of bad press, especially the TDV6.
Stretched her legs on a trip to France then Belgium, just under 1000 miles and didn’t miss a beat.
Averaged 31.6 mpg.
Did develop a squeak from the alternator tensioner, on the return trip. I’ve got one on order.
Couldn’t be 100% trouble free, this is a Range Rover after all
Little picture on the boat.

I don’t normally like RRS’ in Silver or the those “Jimmy Hill” style bumpers, but contrary to that your car is absolutely lovely. That’s a smart looking car. 2006 2.7 TDV6 HSE in Cairns Blue.

Having done three trips down to northern Spain in both TDV8 and SDV6, 2000 miles round trips, I can agree that they're great long-distance vehicles. Never got 31mpg, however!  2012 SDV6 - it's missing a couple of cylinders
2008 TDV8 - it was a labour of love and is much missed
