EDIT [16/09/2016]: The two 'dream machines' have now been revealed as two real life vehicles (a Nissan R32 Skyline GT-R and a Holden HSV GTS) that Xbox Australia will be customising to promote Forza Horizon 3.
Posted on the official Xbox Australia Facebook page, the two cars were showcased in silhouette form, with a confirmation that "something big" involving them will be revealed soon.
The identities of these automobiles isn't known yet, it's incredibly likely that both will be associated with the Australian motor industry – with some users on the Forza Motorsport Forums suggesting at least one could be a ute of some description.
