I know, ancient thread here, but I think there is mis-information that needs corrected for future people that find old threads in their searches for information.
People are saying the "7" following the paint codes mean "California coupe". Doesn't it just mean USA delivery?
Also, if the owner doesn't have a data card, why does he think his car was a California Coupe? The pick of the brown car in the beginning of the thread is not of his actual car, the OP says it is a picture of a car like his. He needs a data card from MB Classic Center (not local MB dealership!!) to know if it was a coupe. I think there was a lot of discussion where there were not facts.
