The interior spy pics are deceiving. The spy pics shows 2 bulbs in the dash like the current 7 series but there is only 1 much like the new X5.
The i drive is second generation with some buttons around it, just like the audi and is positioned right next to the gear switch. The idrive bulb in the spypic is fake. With the B&O like displays I mean black shiny surfaces with orange characters that look like they are projected on the surface from the back, much like B&O in the 80s.
The top dashboard is in leather which is nice.
The door handle on the inside is really strange. There is none.
The trunk is very well shaped and very nice.
The front bonnet has 2 big wedges towards the sides which are high. It makes the overall bonnet very flat.
If you have more questions let me know
