I'd shoot with a wider aperture and a longer focal length in all of them. That way you'll get more subject/background separation. In the last one, the front bumper is cut off slightly. That's a no-no. Also, the car is pointing "out" of the photo in each instance. Try composing differently. They could all use some sharpening. In the first one, the sky is blown out, the car is underexposed and backlit. The second one is pretty well exposed. The last one is underexposed.
#1, bad time for a photo shoot. Wait till evening. The sun is washing out your contrast.
#2 and #3, pretty much the same shot, but with tighter crop. Bad location because of the shadows from the parking structure. If that shot were to work, you'd need couple soft umbrellas to light up the car. Even then, I can see the direct sunlight shooting straight into the fender.
