Yahoo! for Cleaner Cars

Yahoo! Autos has launched a new site devoted to fuel-efficient and alternative-fuel cars (e.g. hybrids, biodiesel, ethanol, natural gas). The sleek-looking Green Center offers "Green Ratings" (developed with help from our pals at Environmental Defense) for more than 100 vehicles, information about different technologies, a gas-mileage impact calculator, links to discussion groups, and tips for moving up on a hybrid dealer’s waiting list.

I'm totally car-less (and a bit clueless about 'em too), so tell me what you think--is this site useful to you?
