The aforementioned Metro XFI is powered by an anemic 1.0L three-cylinder engine producing just 49 hp, but it returns between 55 and 60 mpg. Cars like this defined the phrase 'fuel-sipping' and made passing on the highway a strategic maneuver involving lots of planning. But the XFI is now apparently the holy grail for used car shoppers willing to sacrifice modern amenities and a bit of safety to save a buck on fuel. The trick is finding an example with low miles that hasn't rusted to pieces or been abused by an angry teenager who wanted a Mustang instead. If you do find one, you'll have what automakers are now just unable to offer: a cheap small car that doesn't use expensive technology to achieve incredible fuel economy. But you better willing to pay for it. Thanks for the tip, Lynn!
