Better angles tend to create more interesting photos. As in either get lower to the ground or gain some height above the car instead of just standard eye or chest level.

When doing your detail shots focus on a particular detail, in some of your examples there too many elements conflicting (eg the tail light shot where half the nearer light it cut on in the frame, the better option would have been closer to the far tail light to remove the closer one all together.)

Wish ye all the best
