Many celebrities are interested in cars, often collecting and even racing classic vehicles. "Joyride" features four such celebrities -- rapper T-Pain, NASCAR driver Brian Vickers, actress Mischa Barton and actor Oliver Trevena -- who go on a quest to find the best cars in a variety of categories. Each episode focuses on a particular group of vehicles, such as best British car and best 1960s muscle car. The celebrities combine their automobile knowledge with their driving skills as they test cars to see which ones they think qualify as the best-of-class. The hosts also offer practical advice that viewers can take away from the episodes.

After retiring from his perch atop the late-night TV ratings in 2014, comedian Jay Leno has more time to partake in one of his passions: collecting cars. That is the focus of "Jay Leno's Garage," which showcases the "Tonight Show" veteran's journey throughout America as he searches for unique rides and the stories behind them. Leno explores different aspects of automobiles, including the history of iconic brands, testing supercars, checking out the latest innovations, and even offering consumer advice. He also talks with fellow gearheads, including celebrities, to learn about their collections. Leno says cars, to him, are "kinetic artwork" -- rather than being stagnant, it is art that is "rolling down the highway."
