Simply return the car to the dealership. If there is no mileage or excess wear and tear, there are no other financial obligations. Purchase the Vehicle at the guaranteed residual price. Extend the Lease for up to six months. This can be used as a bridge for customers who want to wait for the new Lexus models to arrive.
Most customers expect and have equity to apply to their new purchase.
This can reduce the monthly payment and the term, giving the customer more flexibility. Flexibility is the key. One of the options leasing gives you is the option to buy the vehicle at term. You are under NO obligation to decide until the end of the lease. The purchase option price is fixed at lease inception.
