well first off real 69 camaros DO NOT look like that, the crease is there, but its not NEARLY that pronounced. The reason that they couldnt do that with the 2010 is if they did the crease would be almost at the top of the door where as on the 69 with much smaller wheel wells the crease meets the crease on the door dead center. Case in point look at this picture of my 69 parked next to my 2010 , if you were to draw the line from the wheel well to the door, it would just look stupid.
