welcome to the XV club, you've had yours a bit longer than mine, I'm not sure the bonnet trim would look right on a dark coloured one, my wife has the dark metallic grey, which is a gorgeous colour as its really metallic and sparkly, also makes the car look a lot more butch than the light colour which tends to look more sporty. its amazing that when mine and my wife's are parked next to each other and they don't look like the same car.
I must admit though that my wife is thinking that next time she changes she might go for a forester instead, so looks like we're with Subaru for a bit now.
I'm still running mine in at the minute so the engine & transmission is still a bit tight, but its still turning 69mpg on the M6 over about 80 miles which is pretty impressive for a permanent 4 wheel drive weighing 1.4t
What I did buy though which we have for both cars is the rear bumper trim that protects the top face of the bumper behind the boot, its about 90 quid but that will get really scratched in no time, especially if you have a dog!
@Gambit - to be honest I'd suggest that the white one is a bit understated for you, I think you'd be more of the colour below (though I've been advised they devalue quicker)
