My people are northern hillbillies I've fired guns into cars. Cars that are on blocks in our back 40. Because bored and we had guns.
Holes all look different. Depends on your fire arm, car, etc
One time out back while doing just such mischief my uncle holstered his 45 and accidentally pulled the trigger (because high) and it put a hole in his arm pit and another one in his leg where it exited.
Holes in people are gross. Specially when they bleed out of the holes when you drive them to the hospital 45 miles away.
