What car companies have forgotten is that there are people who know nothing about cars except that "that ones looks cool, what's it called and who makes it?".
I will admit that I was one of those people.
Muscle cars are famous among even normies because they look cool, they're not in a sea of cars that all are so alike that they blur together.
