#1 needs to be cropped tighter, and you have a lot of blown areas, in particular the bonnet of the car.
#2 is off kilter, slightly out of focus and with a distracting background. It's also a pretty boring shot of the car. If you're doing front on it's probably best to get in closer with a wider angle lens and as low as possible to make the car look more intimidating. Also pay attention to how the wheels are turned, they should be either dead straight, or even better aggressively turned - not turned just slightly.
#3 is the best composition although the background is still annoying, and also looks to be oversaturated. It almost looks like HDR although still with some blown highlights.
