Title: Old technology for high price
Review: Mileage Indicator have been very old technology that came in stock (part of the speedometer) to many vehicles all the way back in the 1999. Eg: most of the BMW 3 series. Plus you could help yourself save money for gas by developing a better driving habit (slow down on the acceleration, keep constant speed, etc...) rather than spending extra 150 for this device that only tells you how much gas you are using. Nevertheless, this device would be highly inaccurate for older vehicles anyways since older car inevitably inefficient compare to newer cars, resulting in lower gas mileage. Common sense, think about it. They might make money of from others not so informed buyer but never from me.
