what color is this car?
 

i think its maroon with a lot of sun hitting hit plus a bad camera.

sport red?

the other two vehicles are the same color(s)

the world may never know

Agreed with your analysis. If you look at the car in the back, they appear to be the same color, but with the sun and position of the car... it distorts a bit.

Or maybe they just took a terrible picture of a terrible painted cameleon Alero... lol
