The Consumer Leasing Act (CLA) prevents dealers from collecting more than three times the monthly payment at the end of a lease.

A dealer may collect a higher amount if the mileage limit was exceeded, or if the car is returned with excessive wear and tear.

The dealer may decide to sell the car after the lease has ended. If the car sells for less than the residual value stated in the contract, you may have to pay up to the equivalent of three monthly payments to make up the difference. You may be able to negotiate the final sales price so the dealer can’t sell the car for less just to get it off the lot.

You do not get a refund for staying under the mileage limit. If you purchase the car at the end of a closed-end lease, you may be able to avoid paying for excess mileage.
