At that time Porsche AG could only paint Pearl White metallic as a real special order and they maintained they could only paint one car per month! Each car had to be taken to the Repair Department who dealt with all the custom work in those days.
At one point we had eight of the twelve worldwide production slots for Pearl White metallic paint that year all destined for Bahrain!
Later this became a much more common colour and a number of other specialist shops started to offer it as well as Lexus amongst others. I still maintain that no one did the colour better than Porsche.
