So, should you be running out and purchasing a used fuel-sipper of your very own? Maybe, but consider that these vehicles would not be able to meet the safety regulations required by law today and the fact that they would likely not pass current emissions requirements. Additionally, the fuel savings of these vehicles makes for pretty poor performance. At AutoblogGreen, we're apt to overlook some of these deficiencies in the name of efficiency, but we also recognize that older vehicles such as these can present problems to their future owners. Our advice, therefore, would be to look hard in order to find a good deal if you're really interested in the ultimate in fuel savings, and remember not to discount the first-generation Toyota Prius in your search.
