Roger has owned his Toyota Highlander Hybrid now for 2 years. He estimates that the hybrid technology which added $4000 to the car’s cost, saves $0.08 per mile based on a savings of 10 mpg over a non-hybrid version of the popular SUV. (25mpg vs. 15 mpg). Driving 18,000 miles per year would result in a savings of about $1440 per year (at $3.00 per gallon) which is equal to a payback of about 2.7 years. For a drive in his car, just sign up as a buyer under his buyer brokerage relationship.
