Is paint protection or ceramic coating from a dealer worth it?

That is a personal call, but understand exactly what you are paying for. Dealer paint and fabric protection packages range from a coating applied at the dealership to a warranty-style promise to fix certain stains or damage, with many exclusions. Ask what product is applied, who applies it, what the written coverage includes and how claims work. Independent detailers sell similar coatings, so compare prices. It is optional, and if it is pre-installed you can still ask about removing the charge.
