2) As I understand it, yes - the black headliner is a result of the sport package only.

3) I have saddle brown nevada. The color is pretty new to US orders so if you really want it in nappa, I'd suggest you ask your dealer about this straight up.

4) Titanium grills are standard on the 4.8i

6) Running boards are $300 if you order it when you place your order. Otherwise, they cost $565 after, such as when you pick up your car but decide you want to put running boards on then.
