General Motosr has released some atrocious chops before but this one really takes the cake. Apparently the trees in the background were taking away to much attention from the C6-R barreling at the camera.
I circled the blatant "touchups", you can see in the large circle, the original background which already looks quite blurred. The trimming around the passenger side mirror is just plain amateur.
What are the diagonal hash marks in the background from? I circled one for emphasis.
And just to show how horrible this pic would look even if it was sized really small for magazine printing, I attached a much smaller version.
