Awards shows: The Green Carpet

SPOTTED: Celebs skipping stretch limos and arriving at awards shows in earth-happy cars from Eco-Limo, which serves Los Angeles, San Francisco, New York City, and Washington, D.C.

WHAT CAUGHT OUR EYE: The Toyota Prius's sporty, sleek lines, not to mention the gas-electric vehicle's 60-mpg rating. The Prius is driven by the likes of Julia Roberts, Leonardo DiCaprio, Prince Charles, Jennifer Lopez and other A-List celebrities, it's widely reported. (George Clooney reportedly drives a Tango.) Ed Begley Jr., Hollywood's self-professed "greenest celebrity" and subject of HGTV's "Living with Ed," gives Eco-Limo the official nod for "the best service and cleanest-burning vehicles around."

GET IT: The Toyota Prius is available at dealers nationwide starting around $22,175. Eco-Limo's fleet of vehicles also includes the gas-electric Toyota Highlander Hybrid and Lexus 400h, the biodiesel-fueled Ford Excursion Turbo Diesel and Mercedes E320 CDI, the Honda Civic GX NGV (natural gas), and the Chevy Suburban (compressed natural gas).
