 The VK series was in production between February 1984 and February 1986 and was the first Commodore to have plastic (polypropylene) bumpers and introduced rear quarter windows for a six-window design (styled by Holden, but similar in appearance to the Opel Senator) as opposed to the four-window design on previous Commodore models.Apart from the bumpers and "glasshouse", other changes for the VK Commodore included a front grille redesign and revamped dashboard instrumentation that included a full digital (vacuum fluorescent display) arrangement for the new luxury version, the Calais.The exterior of the VK Commodore was also updated with a more modern and aggressive appearance.
