BKK,
I support what Alfred said about the rocker panel color.
However, the info on the paint code of the trunk and softtop compartment (including inside of the tonneau cover) is
not correct - or better say
not complete.
For YOUR 1966 230 SL the paint code for the trunk, softtop compartment was
black, not tiefdunkelgrau 7164.
Tiefdunkelgrau (deep dark grey) came only later, sometime in 1969 or so.
Don't let yourself be fooled by this 280 folks who claim that everything they find on their original late 280ies is also correct for the earlier 230ies and 250ies. This is
not true.
I have seen
enough 230ies and 250ies with totally untouched trunks and softtop compartments as well as early 280ies.
And those are
black inside, not dark grey.
It is your car you can paint it anyway you want!
Alfred is right with what he said, it's your car.
If it were mine I would do it original, and that was/is black, and that's what my car is now.
I know the stories about deep dark grey appears to be almost black. Fuggettaboutit. I know what tiefdunkelgrau is, my 1971 230 sedan has that paint code and it is
clearly different.
It's your choice, do what you want.
I go and change the info in the wiki, it's not complete there.
As a board member for almost 10 years and a Pagoda owner for 29 years
I am absolutely confident about what I just mentioned.
Just my 2 cents ....
