The car of your dreams: El Supremo
NicoleC, the Camry figures are correct- a number of manual transmission cars are poor on greenhouse gas emissions relative to automatics, and Camry is one of them. Why this is, I don't know. Possibly the manufacturers haven't kept them up to date.

Amos, hadn't mentioned the Toyota Corolla, which is different from the larger Camry. Models, acc. to government figures, average 30 mpg city, 39 mph Hwy, and get a green rating of six - the same as a Lincoln Towncar. At 25 mpg, your car is below average (I picked 2001 for model year). At 25 mpg, you must be a hard driver, the average is more than 25 mpg.
Remember that some of the little 4-bangers put out more emissions than the higher performance sixes; mileage may be better but because of the emissions, the greenhouse ratings are the same or even slightly worse.
