In auto leases, the number of miles you can drive without penalty. How many miles you’ll be allowed to put on a leased vehicle is one of the most important conditions of the lease. Some leases can tempt with low monthly payments because they allow only 10,000 miles per year, but try not to sign up for anything less than 12,000 miles per year or try to negotiate for that amount for the same payment. If you drive a lot or have a long work commute, 15,000 miles of annual driving might be even more realistic. Remember that the more you drive, the more you’re depreciating the car. So higher mileage limits usually lead to higher monthly payments.
