BTW, part of my issue is that the images need to be taken right here on my driveway as shown and/or in my garage, because the car has only 351 miles on it, so driving it to a better location could be very expensive as I'm sure most people know that adding miles generally devalues collector cars. And I don't have a trailer for it. That said, I could prob rent a trailer, if you all think this environment is poor enough that a change is needed ... ?
Looks good! I can see that you like to show the details of the undercarriage. For those who don't understand, that's one of the reasons why we edit photos.
I'll show you a little of what I did. I used Gimp, but PS should work in a similar way. Here is the color adjustment tool in Gimp. (It's called that, but it can be used to adjust composite brightness, as here.) It's a beautifully designed tool that allows complete and easy global control of the brightness values. I clicked on three spots on the body, to show you the brightness values on the histogram. I marked three spots with dots and a line. On the left is about the darkest spot on the body, on the bottom of the rear fender. On the right is one of the bright reflections. The vertical line show the deep red near the top of the rear fender.
From left to right, the three dots on the straight-line curve show brightness of: underside of fender; top rear of fender; reflection on fender.
Here is the approximate (recreated) adjustment I made to the body. The split screen shows the effects of the adjustment. The curve is a little steeper in the middle portion. That darkened the dark areas a little and brightened the reflections. In so doing it increased the contrast in the red paint, and made it look a little richer. (I'm sure it really is a rich red paint!.)
The split screen shows before and after adjustments; the vertical line on the picture is moveable. Oooh! Aaah!
Adjustments that were applied to the body
Here is the recreated adjustment I applied to the front wheel, and later to the driveway. I needed a fairly strong adjustment to the bright areas to show nice detail in the wheel, while still maintaining bright highlights.
Adjustments to the front wheel and driveway
I also did a little burning to the midtones around the racing stripes and logo. That isn't shown here, but it darkened the red a little in that area.
I'll just leave you with some suggestions on some basic skills to learn. These are the bread and butter of photo editing, and they aren't difficult to learn.
I already showed you the brightness and contrast changes I made. Next, you need the skill to apply these brightness and contrast selective to selective parts of the image. You may want changes in one part of the image but not another. You need to be selective, and you need the skill to blend your changes without visible artifacts.
First, dodging and burning is
the classic technique in photo processing. You wave a fuzzy brush around parts of the image to darken or lighten parts of the image. With digital processing you have your choice of the image range to operate on. You can also choose the size and shape of the brush, fuzziness of the edges, and strength of the operation.
Second, uaw of layers is a beautiful and very useful tool to learn. Basic use is not difficult, but of course you have to learn what some of those inscrutable symbols mean. Here is the Gimp layer tool. I created three layers of your car image, then made some crazy edits to the two lower layers. Then I created layer masks and spray painted parts of the masks black, to create fuzzy windows to the layers below.

Good luck with your editing. I'll leave you to it.
Not nearly as sophisticated as your edit, but would you be willing to comment on my try?
