It should be left completely up to the consumer. A sales person will rely on the fact that the consumer is not knowledgeable about the facts when making the argument a convincing statement.
Commonly, a consumer will be told of the low interest rates, the minimal down payment, and the low-low monthly payments. This is done in the same manner as dangling a piece of candy in front of a child. To lure them in and make the sale. When leasing a vehicle there can be many hidden costs, for example high repairs and regular vehicle maintenance, costly over mileage charges and early lease termination to name but a few.
Another cheap trick that is ranked fairly high on the list is the premature car lease termination process. This is not at all stress free as the dealerships tend to let the consumers believe.
There are hidden costs involved with terminating the vehicle lease before it is scheduled to end. This process itself could actually wind up costing thousands of dollars as opposed to the $300 that many dealerships tend to say it will cost.
Once you have signed the car lease agreement it is very expensive to even attempt to get out of the contract. Be sure to read all of the fine print prior to signing anything.
Do not allow the sales person to tell you what it says, read it for yourself. This is another way that the dealership can get you. By reading everything, there should be no surprises in the long run.
