The picture with the two Mustangs is Renee', this we know, the question is not about the photo with the two Mustangs it's about the photo above that, the one that is an advertisement. they want to know if the car in the advertisement is Renee's car, they added the photo of Renee' and the other Mustang for comparison to the advertisement to see if they are one and the same car. At least that's my take on what the question was.
It sure does look like her car, not sure I've see any other blue CS's with the dark argent color in the center of the styled steel wheels.
