Okay, here are some option prices that I just got from my local dealer:

Rear side sunblinds - £200

Park assist - £350

Premium sound system - £300

Heated front and rear seats - £325

Privacy Glass - £205

Auto dimming rear view mirror - £50

Obviously, some prices will only apply to S and SE models (like heated front and rear seats). The park assist price applies to Elegance models. It looks like it will be £450 on non-Elegance trim levels.

Odd though it seems, not even the Elegance gets the auto dimming rear view mirror. A curious oversight.

Bagpuss.

Sunroof is £550 and the solar panel sunroof is £680 I think.
