We can get something like this

with these "basic" settings

exposure: +0.20
contrast: +15
highlights: -15
shadows: +10
whites: +35
blacks: -35
clarity: +5
dehaze: +5
vibrance: +10
saturation: +5

and a vignette 

exposure: -1.0
contrast: -15
highlights: -15
clarity: -15
sharpness: -35

One tip, after selecting a profile (generally any camera matching one, instead of Adobe defaults) making an initial WB setting, initial tone settings(exposure, white, black, etc), and an initial tone curve selection, adjust the WB again, but use the sampler tool (eyedropper) to accomplish that. Remember you do not have to select a nice white (but not absolute white) area, or a gray area (as in gray card), just a nice bit of image with a near solid color selection. However, what a nice large source of neutral gray in the background of your image.

Small corrections in WB can lead to huge improvements in perceived image quality.

While that is a good final result, how to get there greatly depends on where you are starting from with the original file.

Can you link us to an example of yours?

I suppose it's a matter of personal taste. But if the beautiful car is the real subject of the picture, perhaps it would be a good idea to try to make it more prominent. Just a suggestion.

I know many car photographers like to play with the "Clarity" slider.  I would try and use this sparingly. Values of 20+ begins to introduce uneccessary contrast.
