How can we trust the mileage per gallon posted for the car being sold on CarGuru?
What sort of protection do I get against getting cheated on?
The EPA gas mileage website is the place to double check fuel economy numbers.
How will that help? Are you talking about new cars? I'm asking about used cars.
The EPA has the numbers for cars going back years. If you want to know the EPA numbers go to the source! https://www.fueleconomy.gov/
