When you have money available, the best way to use it is to invest it in your mortgage, your retirement fund or pay down high interest debt like a credit card. A vehicle will depreciate over time and if you pay cash, that depreciation is your money disappearing. Leasing provides a way to have low payments, pay only for the usage or mileage you need and keep your cash for more important needs. With low interest rates on leases, you may even make more money just keeping your cash in the bank and using the low lease rate available. Regardless of the mileage you drive or your budget, leasing provides a great alternative to paying cash.
