Asked about it at work, because I test drove one....a 645CiC with SMG.
1) The fixed hardtop is coming. Not avaiable yet, but coming. I specifically made sure they knew what I was talking about because we had a Z4 Convertible that HAD the fixed hardtop IN, but not installed....sitting next to the Z4 Convertible...so yeah I made sure they understood what I was asking.
2) No M/Performance package....but the 6ers have a sports package....ones with 19s. And the sales guy said you prolly could get a BMW spoiler...I liked SMG...if you consider that sporty...and it's an option included in the price of the 645CiC (i.e doesn't cost anything).
Sport Package
Active Steering with variable steering ratio
19 x 8.5 front, 19 x 9.0 rear Ellipsoid (Styling 121) cast alloy wheels, 245/40R-19 front, 275/35R-19 rear performance run-flat tires1,6
8-way power front sport seats with manual headrest and thigh support.
So yeah....that's what I found out from my end. Maybe it's different where you are.
Good luck!
