I found a website that has all the makes of cars, and their advertised mpg, and their tested mpg. Me and the wife were checking out all the cars to see who has the best, and we decided to see some older model cars, to compare. We looked at the 1985 models, and found that every car made got better mpg, than any car made after 2000! Even cars like the cutlass was getting better than 20mpg back then, i would think with our modern technology, we should be at least 25% better now!! Check it out www.feuleconomy.gov
