Unless you plan to keep your Prius as collectable 25 years down the road, otherwise, this extra spending does not prevent the vehicle from depreciation to zero value after 10-15 years.
It doesn't matter whether you keep your Prius for two weeks or two centuries. Teflon coating is a joke! There is no way that teflon can be put on a car that has already been assembled. As slick as it may seem on pots and pans, it has not been proven to do one darned thing for an automobile finish if it is suspended in some sort of wax or polymer. It is like eating paper clips to get your daily iron! It is just not in the right form. PERIOD!! All of those finishes pushed by dealers and distributors are just simply profit centers or a wierd form of insurance, where they GUARANTEE that the paint will last X number of years IF you wax it every certain amount of time. Almost all paint nowadays will last quite a long time and almost no one does the required maintenance. The few claims they have to pay are just a dot on the huge profits they have already made, and that is if they are still in business. Pay someone to wax your car with the money and you will be way ahead of the game.
Are you saying that people should pay to employ someone locally to make there car look better instead of encouraging unethical business practices that do nothing for the car? That doesn't make sense. My toyota dealer would never sell me something that didn't work just to make money ;-)
