A fourteen dollar daily rate sounds like a great deal for an mid-size rental car – until the total for a three day rental comes to $83.56. That’s right, 98.95% in taxes and fees. If that seems excessive, one can always get to a lower percentage by renting a Mustang Convertible for $210.64 per day or $842.04 for three days – that’s works out to only 33.25% ($210.12) in taxes and fees. But the most disturbing part is the inaccurate calculations used for taxes and fees. With errors that never seem to work out in favor of the traveler.
