You can also use "Color Balance" in Photoshop under adjustments I think (where brightness and contrast can be adjusted) to correct the photo for different lighting situations)
But for digital it's best to adjust the setting on the camera first rather than having to fix it up later.
after looking at your photos again i'd have to say this one is my favorite,
you really get a sense for the shape of the car.. the shot also stands out from the rest of the pictures and shows you took a good look before taking that picture
