Say what you want about the Miata, but the Miata and its newer MX-5 siblings are some of the most frequently raced cars in all of motorsports. Some see them as underpowered cars for hairdressers, but well driven they can be some of the fastest cars on a racetrack despite significantly less power than the competition.
A dude named Brian Young has purchased a Miata for $1000 with plans to turn the car into some sort of drift racer. As part of his getting the car ready, he put in an ignition that requires quarters to start. As you can see in the video, he drops in the quarters and then the car will fire up.
