The Wraith movie car was based on the Dodge M4S Turbo concept pace car. It was a one of a kind million dollar super car. They couldn't use the actual M4S for driving so they built several mock ups for the film. There are different features on some of the cars (some were just rolling chassis) and the poster/box art as well.

I struggled with a starting point for this custom. I literally trashed 3 cars that were just not close enough. I got lucky when I saw that the interior of one of the cars would make a really close outer shape.
