all of the warranties you can purchase as long as you are still covered under the factory warranty. you have 3 years to decide for the maintenance, and 4 years for the warranty.
all of the other stuff is horribly overpriced.
tint, xpel will only sell through their authorized dealers and there's exclusivity agreements, so its not going to be hard to find out who they use. there will be only one authorized dealer within X distance.

pretty sure thats who they use for tint and ppf. i would read their reviews and contact them directly. in NYC a high end ceramic tint on all windows is under 1K and thats including the pano roof.
