I find the lack of distinction between the top of the hood and the sky to be very distracting, as are the reflections ni the paint, including your own. Perhaps a polarizer coudl have prevented that?
Nice colors in the shot, think it is a bit too tightly fitted in the frame though, I would have preferred it if you either had taken a sligthly wider shot and had more space around the car or just taken a closeup of it, it´s just to "cramped" for lack of a better word.
Reflections .... when photographing cars the enemy is reflections. I usually ask the driver to move the car which you would be surprised at how many agree. If you are taking an interest in the pride and joy they are usually more than happy to help.
