Hottest Rides Countdown - S19.E9

For this countdown special, we're buckling up and punching it–as we raid the Modern Marvels archives for the hottest rides we've ever presented. From the retro to the rugged to the reckless, our top ten picks showcase our love affair with vehicles that blow back our hair or quicken our pulses. Our only limitation: they've got to stay earthbound–so no sea or aircraft. Other than that, anything goes…from one of Jay Leno's vintage autos to a sleek battery-driven roadster to a motorcycle you've got to see to believe. Our number 1 choice: a ride so hot that one passionate owner applied for a license to marry it.
