Anyone who goes out and buys a new hybrid car to prove how green they are is missing the point -- a better way to live green is to keep your old jalopy as long as it's practical, rather than encouraging the manufacture of new cars (even if they get 45 miles to the gallon).
And as long as you're hanging on to Bessie, keep that bucket of bolts as efficient as possible by taking good green care of her. Regular tune-ups, smart tire maintenance and other basics of car care will keep the ol' gal running efficiently for years.
