Hey, I can't help you on the modeling of the car part seeing as how I haven't modeled a car since GTA IV days, but if you don't hear from a modeler I may be of some help.
If you don't hear from somebody, try to find a charger model that you would be satisfied with using (possibly BxBugs123's chargers?) and send me the link, and I can make a texture for you (you can look on my profile for pictures of a North Carolina State Highway Patrol '15 charger I skinned). You (or I) could also replace Bxbugs123's charger hubcaps textures with a black ones to match the rims in the photos.
If you decide to go this route I could have the skin ready in a few hours - a day
