You can buy nearly anything from vending machines — soda, ramen, headphones, and now, a new set of wheels. Located in outside of Nashville, the Carvana Car Vending Machine lets you buy a vehicle using nothing but a coin. A very expensive coin, most likely tied to a loan, but still. Insert your giant, personalized piece of change and a huge robotic arm goes up and grabs your car, then hands it off to another 'bot that drives it down a hallway to the pickup bay. It's the most exciting car buying experience since the stunt driver took Luke for a test drive in Used Cars.
