Does anyone remember the Dodge Stealth? One of the models had a spoiler (a small one, about 2 to 3 inches deep and full width) at the leading edge of the rear decklip. That is the kind of spoiler I would want on the Intrepid. That would help to maintain laminar air flow of the rear, and could reduce lift/drag on the rear. Due to the virtual axis trunk hinge, the spoiler would not hit the rear glass when trunk is open.
