I'm a little while from ordering, but I think the spec I will go for will be:
RCD510 + Dynaudio
ACC
Xenons
Winter pack
Monza Shadows
Cruise
Could lose the Xenons, but quite fancy having them. Everything else is a must have.
Non-essentials (to me) that I would love to add if money was no object are leather & nav.
Oh, and I'll take it in red please

The white does look the dog's, but mine would spend too much time filthy I think.
