The license plate is KSA (Kingdom of Saudi Arabia).

I recall a forum member from there or moved there from the US.
May be he can enlighten us as to what is the deal with color.
Could be the "latest fashion" there.

But then again, the car is in France (most probably Paris or Lyon)
and the driver is trying to make a statement with purple color.

I, personally, would not drive it. If I get it as a gift, I would just sell it.
