My blue WB had a strip above the rear window that never had paint on it.
Black cars are good. Our last Prado was black. Never washed it and it was always on dirt roads. It looked unreal as long as you only looked at the paint in the dark. Scratches all over it if you washed it.
I still like the idea of a genuine Tuxedo black Sandman or hatchback Torana though. Toughest colour for sure.
