The Calais Wagon was not officially produced by Holden until 1988, but HDT had modified a few Berlina Wagon’s and given them the Calais treatment long before this time. However, unless a minimum amount of modifications were carried out, the cars were not allocated a Build plate.
HDT also created some Calais Sport Wagon’s, one of which was fitted with a 5.6 stroker V8, while various body kit pieces were fitted to the different cars. However, many of the non plated cars had no body modifications at all and merely looked like the Holden produced Calais Wagon’s
