Limousines have become more about bachelorette parties than star-studded premieres, so Adam, Rutledge and Tanner decide it's time to get some of the glamour back by building their own. To find out which is best, each of them has to transport a celebrity to the Primetime Emmy® Awards.

The hosts buy each other what they think is the worst car in the country and set themselves a challenge--whoever can make the car they've been given coolest and sell for most money at an auction at the end of the journey wins. Tanner travels to England to find out just how fast a brand new supercar--with no official top speed--can go.
