If you are thinking about a car lease in Plainfield, you might need a little direction. What is a lease, anyway? Well, it’s best to think of a lease as a long-term rental. Basically, you are “borrowing” a car from a dealership, and in return, you give them a monthly payment. The length of the lease varies, but in most cases, it is 24 to 36 months. When you are done with the lease, you can either return the car or you can buy the car out and start making monthly payments towards ownership.
