What Am I? One of One

You guys are really good at solving the What Am I? puzzle..so I’ve got to start playing dirty. Guess the make/model of this concept car.

Comments below.

UPDATE: It took some time, but Kaibeezy and [correction] Dr. D cracked this one wide open!  I did two things, first a color shift to blue (just because I am a jerk) and then I cropped it so that the passenger headlamp looked like it could have come from the driver’s side.  Pics of the 1955 Chevrolet Biscayne from the Petersen Auto Museum I snapped last week.
