As far as inanimate mechanical objects go, the car has got to be in the top ten when it comes to being associated with coolness (i.e. verility, youth, sexiness, etc.). Perhaps, only the electric guitar and motorcycle can top it. Sure, you've got your "chick repellents" like the Brady Bunch station wagons and AMC Pacers; however, these are easily countered by a 1966 Pontiac GTO or James Bond's Alpha Romeo GTV6, which literally do not need gas to run, but rather are powered by their own raw sexual energy.
This is especially true for the muscle car. Harken back to your high school days: even the goofiest guy could get the grooviest chicks if he drove a badass Plymouth Barracuda. Indeed, the sexual power inherent in these vehicles is so intense that some say that if a hybrid minivan comes into contact with a 70s muscle car, it will have a matter-antimatter reaction, creating a tear in the universe. Don't try this experiment at home, kids.
