Tim,
I'm with you on the 18" wheels, PCM and PASM, but personally wouldn't have the tow bar unless you deffo will be towing and also can't see the point of the roof bars. I'm also unsure about the sunroof, although SWMBO wants one - what is it with women and sunroofs?
Anyway, all the options I have ticked are:
PASM
18" Macan S Wheels
Metallic Paint
Bi-Xenon + PDLS
Privacy Glazing
Adaptive Sports Seats
Front seat heating
Park-Assist with reversing camera
Adaptive Cruise Control
Lane change assist
HomeLink
Heated steering wheel
PCM
Mobile phone preparation
Loadspace management
Panoramic roof
Which all comes to a hefty £9,836.00 but as you say, we have at least six months before finalising the spec, so plenty of time to change.
