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.
