1. The “California” was meant for California model, it was a thing to do for Mercedes-Benz during those years.
2. The order number that you gave, is this for a particular model? When I did some research seams like different sources have the same first sections matching (S-0473-XXX) but the last three (02Q) I see other numbers like 97K, 00N, 98L. What does this mean different books for different years, models, or content?
