Only 2 cars were concerned, so I corrected them: the Porsche 718 (2016+ 718 Boxster / 2017+ 718 Cayman), even if mainly facelifted versions of the former 981 models, have the 982 factory code.
Lot of websites and several Wikipedia pages already identify them that way (en, de, it, sv...) and, above all, Porsche's corporate site does it so too (de, fr).
