I've had the car for just over a week now and driven just over 500 miles so thought I'd post a quick review of my thoughts so far.....
Oil dilution: 500 miles driven, distance to next service 15,600 miles. So far, no problem will continue to monitor.
Adaptive dynamics - wow! love it! You can't tell that anything changes but the car is flat in all corners no matter how hard you push it but smooth as silk over bumps in the road. Tight in the corners like a sports car but without the harsh ride.
306bhp SDV6 engine - very nice! Still running in so haven't pushed it hard yet but even with a light right foot it's much quicker than the D4 I had before. Very responsive pickup and crisp response pulling away from junctions. Very quiet but with a satisfying deep burble. Mpg seems good, over 30mpg even on country lanes with steep hills and lots of bends. The D4 would do low 20's on this type of driving. My usual commute currently has road works so a lot of standing traffic - too much for the stop start to stay stopped so only getting about 25mpg for this.
Adaptive headlights - very clever. They don't swivel with the steering like they did on older cars instead they change which LEDs are on or off to change the beam pattern. At slow speeds both cornering LEDs are on and the long range middle LEDs are off. Speed up and this reverses so the long range LEDs are on and the cornering LEDs are off until you turn the steering then the inside cornering LED comes on. The auto high beam assist seems to work well and the cornering LEDs still come on with high beam active.
I haven't tested it off-road yet so can't comment on the off-road capabilities compared to the D4.
Seats and driving position are very comfortable. Infotainment works - no glitches so far. Driver aids seem to work well, except park assist which seems to make very hard work of getting in to a space where I can park neatly in a single move and ignores spaces that I can park in no problem. I can't see me using it much.
Load space is perfect for all of my work kit. It hasn't got the height or width at the top as the D4 but that isn't a problem for how I use it. I might need extra lighting in the boot as the winter nights draw in.
I still haven't found a phone mounting & charging solution that I'm happy with. I've got one of these on the way to try....

I think I've figured out how to mount my CB for off-road use but haven't fully tested it yet.
