Hello Sidney,
Welcome to the group.
Since your signature is not referring to any pagoda but your pic is - maybe you are looking for one?
The California Coupe without softtop compartment is not so uncommon as sometimes pointed out.
These cars are usually less valuable among collectors because of their missing soft top.
However, this can be retrofitted with some effort although this was not designed for that by MB.
Anyway,
ah no, unfortunately there is no statistical overview about this from MB.
Good luck,
Achim
