Not ever having owned a classy car before, I'd appreciate any tips from knowledgeable folks about the most efficient way to keep Model S looking great from a total cost of ownership and time spent perspective. I'm relatively naive about taking care of a nice looking car and don't have time or the knowledge to do my own detailing, as I'm sure is the case with many people. So I'm wondering about what the best plan is. Is it most efficient to have a space age polish applied professionally upon delivery followed by regular exterior washes and periodic reapplication of the polish? Or does a paint armor film of the entire car keep the paint and finish underneath pristine and the car looking best? If you have paint armor do you need to polish or wax the car or do simple exterior washes do the trick? If so is it cheaper and more time efficient in the long run to armor the whole car? Bottom line: What's the most cost / time effective way to keep Model S looking the best most of the time for the most years?
