If you have Photoshop, you should have Adobe Camera RAW (ACR). Even if you shoot jpegs, you can still open them in ACR. The ACR sliders are almost always sufficient to correct most images.
As far as composition, you can see that when the haze is corrected, the mountain behind your car is stealing the viewer's eye away from the car. It's a hard thing to remember (I still forget), but you need to always consider your background. Here a longer lens would have created a shallower depth of field and left the background slightly out of focus (OOF) and then your car would have been the isolated subject.
I'm certainly no expert on car photography. I leave that to John Zhang. But look at some of his amazing work
and you'll see how the car's surroundings can make a picture interesting without stealing attention from the car itself.
