It's the little triangular pieces on the left and right edge of
the dash which are only visible when the doors are open...

Thank you MAcarbon!

PS: Ignore the wiring from the telemetry system, which is
plugged into the OBDII connector below the steering wheel
and has its cameras on the passenger side window corner.

 

It's one of those small touches that to the keen eye makes a huge difference.

 

more interior shots please!
