There are plenty of them with male models. The ones I have done photo editing for have been mostly for the Police vehicles though.
You also have to remember that muscle car advertising is mostly targeting men so that’s why female models are so prevalent.
There is also a misconception that Male models have to be super buffed and even look kinda gay......I think I like a good looking regular guy better. A guy that is something you would find at a car show or out on the street cruising.
Older guy with a good fashion taste, and good taste in cars. ...... kinda like moparmitch just as an example.
