<prompt> Human: This sub is full of ways dealers coerce or even trick buyers into purchasing extra stuff they dont need when they get you in the back room to do the payment and financing for a car.Question is - Are there any optional warranties, service contracts, whatevers, that you think are actually a smart buy?  <response>: If you are JUST talking about addons that come on paper not really, very little will pay for itself.If you are talking about the hardware of the car itself then yes as you will never have the option to upgrade to a different trim level, bigger engine, or better transmission later.
