You will need to pay an extra charge if you end the lease before the completion date based on the difference between the estimated residual value at the end of the lease and the actual residual value at the given time. This may be a large difference. Most agreements state that you must have the car for a minimum of 12 months.
Before you sign the contract, the dealer must tell you whether you may terminate early, and the cost of early termination.
