that isn't a photoshop. first, look at the lighting. the old photo looks like it was taken at sunset, or sunrise. the new one looks like it was taken in the middle-late afternoon. the lighting conditions change so much about the picture, including the reflections on all the body panels, windows, headlights, and the ground. emulating that change in lighting perfectly is unimaginably difficult if not impossible. look at the all of these reflections - they're completely different, and they're perfect.

besides this, please look at this image i just put together. the comparison image posted above selectively compares sections of both cars to make it look like they're from the same original photo - but this is not so. look at the hood line, the driver's side headlight, the trunk line, and the front fender where the side marker is. they're all completely off. if this was photoshoped then whoever did it essentially photoshoped an entire car in, which is beyond reasonable expectation. they just put the car in the same place as before, and happened to position it and the camera at almost the exact same spots.
