Im about ready to purchace a 2022 Legacy.. Two questions: Is the Reversitall safe on windows and body of car? The dealer says Reversitall is on Addedum as well as window tint. Also I am wondering about sunroof.. I want the Legacy Lmt. Package and it comes with sunroof. i expect this will be my last car since I am 65. Is there maintenance to prevent leaks etc? I live in southwest so not much rain but lits of sand and sun.
