Yeah, I think it's a top idea too.
I don't know how far it was discussed before, but from my experience of these things - If you come up with a fairly simple good design that can be cut in vinyl, any sign maker can make them up fairly cheaply from a master on a disc.

.......in a Land Rover style inside an oval? Not too huge, but big enough to be noticed & expand membership (4", 5", 6" ?). Just a fairly simple idea & just my thoughts.........
Say in red, green, yellow & black to cover all schemes?
Get quotes for 10, 20 etc, payment up front?
I'd put one just in front of each door, under the Landy logo on my wheel cover, on my rear window.
Any advance?
Best,
Marcus.
