I have a 2015 Mk7 (purists call them a Mk6 facelift.) 3.0 D4D and I love it. In term of toys and tricks, they don't really have any. They are quite basic. I really like mine. It's very smooth and quiet on the motorway, handles very well for a long vehicle and just now I am getting around 30 mpg since having an injector replaced under warranty. Service interval is 10k. It's comfy, roomy and has more or less just what you need. In the snow it was staggeringly good. The Bridgestone tyres it comes with are rubbish. I now have Cooper AT3 Sports on there and they're good. Load bed is 2m so not as long as you might think. With the canopy on there you have to drop the tailgate to get planks and things in it. In terms of longevity, there's nothing I could really call out. Once we're truly done with winter, I plan to get the underside thoroughly jet washed off to stem that typical UK corrosion.
I'd say that the ride for rear seat passengers is a bit hard because of the leaf springs. But with 5 bags of sand in the loadbay, it's much improved. I have a manual but only because that came up first. The auto is lovely to drive.
It has low range but only a transfer box rather than a centre diff. Surprisingly, there is a good bit of latitude on turning. I thought turning the wheel would be difficult but even on tarmac, it's quite forgiving.
