I agree with Groom on these options. In fact, sporting leather interior, I would generally opt for heated seats.
Midnight blue is a very elegant paint sample, in fact I am not sure if it would get along that well with the aero package, which, in my eyes, only looks good on the GT3 (which features additional vents and slats at front and rear).
I was under the impression that Lapis Blue was a special order colour, somehow it must have slipped into the paint-to-sample folder. If you go for the aeropackage, I'd consider GT silver.

Welcome onboard & good luck ordering...!
