In most cases, only certified pre-owned vehicles that were released within the last four years and have 48,000 miles or fewer will be eligible for leasing. Leasing a used car allows auto shoppers to get a substantial monthly discount on a car that’s still relatively new and has well over 100,000 miles of life left in it. Leasing used means the previous owner went ahead and paid most of the vehicle’s depreciation for you. At the end of your lease, you might be surprised to find the buyout price is actually lower than what the car would normally be selling for on the market.
