Unfortunately, those pics are rather plain. There is nothing special about them, really. Not trying to be rude or anything like that, just honest.
I’m far from a car photographer, but, angles, lighting, location, reflections, perspective all play a role in the image of a car.
For example, in the first image, you have the yellow bar sticking out of the roof of the car, with all sorts of odd reflections/blown highlights competing for attention with what looks like a really well maintained car.
In the second pic, it just looks like a capture in a car dealership or workshop. There is nothing screaming ‘wow’ in that image, even though it too looks like a really well maintained car.
Compare that to something like the image linked below from a photog. that shoots cars.

It has depth of field, dramatic lighting, color, etc. Took some time to plan and shoot, to get that image for sure.
My point, beyond all that, is just keep shooting till you hone in on a ‘style’ that fits what you imagine the image to be. Play around with depth of field, lighting, filters on lenses, flash photography/light painting, dark alleys with cool lighting effects, etc. etc. One you’ve got that ‘style’ down, that’s when people with cool cars will start contacting you, versus you chasing them down.
Hope that helps in your endeavor!
This is my body of work, just for reference. It took me years to perfect my skills, and even now, they aren’t anywhere near perfect. Always learning, I am.
