A traditional lease includes a base number of miles - usually 10,000-15,000. If you exceed that number of miles in your lease term, the leasing company typically charges $0.20-0.25/mile penalty when you return the car. Sometimes this can cost thousands of dollars.
If you own that vehicle, every mile you drive will ultimately cost you a few cents in terms of wear and tear on the vehicle. Instead of paying little by little, you end up paying by way of large repair bills. According to AAA, the average cost per mile for gas and maintenance is 20.5¢/mile.
Our mileage fees, which reset every month, reflect the true cost of driving. However, when you add up the monthly fee, the mileage fees, and the cost of charging, every mile you drive still costs less than an equivalent gas car or equivalent EV lease.
