Technically they're okay; try for a location with a less distracting background and consider using a polarizing filter to remove/reduce the reflections in the glass.
I'd try going for a really low angle and shooting into the sky with a ND or HDR process. That would give you a more interesting POV than what you see by just standing and looking at the car.
People see cars everyday. So for you to make them interesting, you have to change up your angles and find interesting backdrops or lighting. Keep shooting!!
