The :30 commercial shows a perfectly '70s yellow 1st gen Civic 2-door CVCC stylishly motoring down a city street to a funk guitar soundtrack. It then parks at the curb and the driver exits wearing a "save the earth" T-shirt. The camera then follows the driver walking down the street through various eras of "save the earth" T-shirts to the present day, where he hops into a new dull gray Civic and drives off.
The 1st gen gets far more screen time than the 8th gen! It's a pretty overt nod to nostalgia. Too bad they didn't have time to explain what made the CVCC such a 'green' car back then, aside from just being fuel-efficient.
