The VX Aero was available for the entire range of VX Commodores. Starting with a Dealer or Private VX, HDT set to work enhancing the vehicle. A tilt-and-slide glass sunroof was there for the taking along with the two tone red and gray leather seats with matching door pockets, colour coded facia panels, body kit and the Milano alloy wheels. Before the launch of the Aero HDT built a promotional vehicle based on the VT sedan. This came with all the enhanced goodies but ran the earlier 5.0 litre motor. The Aero featured an all new bodykit design by Len Pennisi and was available in four engine options as listed below.
