Did you get the small (6X10X2) black zippered leather pouch containing the owner's manual, radio manual, and service schedules from the previous owner? The "cards" are usually stored in this pouch. There's an awful lot of important information in those "books" and if possible, I'd persue the previous owner / dealer to get them. Look all over the car; as the pouch may have been thrown in the truck or in one of the storage areas. ttt
