Sd I buy corrosion protection, paint sealant?

The short answer, IMHO, is no. If you feel you need that type of protection, you can DIY a lot cheaper and get the same results.

I think it's generally agreed upon around here that these dealer add-ons are pure dealer profit, and pretty much worthless to the end buyer. If you are concerned about the underside of the car (you have a lot of road salt during the winter or something), talk to a third party about it, you could probably have it done for much less. for the paint, Zaino seems to be about the best thing you could do. For the interior, i purchased a few cans of Scotch Guard from Lowe's and did it myself. The dealer can't really do anything more than that, and it's only a few minutes to apply.

 

A friend in the car business told me the "protection" package was worthless. the only upside was the once a year detailing, but you can get that done elsewhere......

All worthless. Some are actually harmful. Everything is pretty well protected at the factory. The aftermarket stuff is all redundant, and the aftermarket undersoating can actually trap moisture and accelerate corrosion.

The extended warranty is a form of insurance, but is overpriced. If you are inclined to worry about post-warranty repairs it might be worth it for the peace of mind, but, like gambling in Las Vegas, the odds are against you. I.e., you are more likely to come out behind with the extended warranty.
