invisible car design

[Benni]

There once was a car design company in Rhein-Main area.

They were sooo upfront in design that they invented invisible cars

before becoming invisible themselves.

Clever, huh ? I hope that no other PHer was involved and is now looking for invisible payments.

I am.

Hello Paul,

funny that you come from nrw, this company still has an office in Köln

but of course the other one was operating totally independent.
