Options I ticked (and am massively happy with) aere...
Performance pack - well worth it for the diff, the pull out of corners is amazing and I've yet to have the inside wheel feel like it's got no grip.
Leather - expensive but I really don't like the check cloth, however does get very hot out here in Cyprus.
Rear view camera - Great for not having a blind spot right behind you, although not a replacement for actually looking over your shoulder.
Park assist - not for the actual park assist, but for the extra parking sensors that (I think with some computer trickery) give you 360degree parking sensors.
Keyless - a boon, especially if you've got your hands full. I never need to take the key out of my pocket.
