Among the cars to be unvieled Aug 16 at Woodward Dream Cruise in Detroit will be PT Cruiser Dream Cruiser 3 - which will be a 2 tone model
Midnight Blue over Silver - with Transaxel drivetrain.

There may also be prototypes on display as well like the PT Convertable and maybe a Crossfire Convertable.

Not sure of any other models but I did see the PT pickup at Cruise the Falls which has a V10 viper engine in it.
