Essentially, you don’t own the car when you lease; you are renting it. When you lease, you agree to have the car serviced according to the terms of the lease. If you don’t service the car as stipulated, it could void the warranty on the car, and by voiding the warranty you could be required to purchase the car outright or lose it. You really need to read your lease agreement to determine what will happen if you don’t. You should check with other Toyota dealers in the area to see if their service fees are the same.
