The rubber on my 2019 countryman’s rear window trim has dry rotted and is falling away in chunks. I can get replacements from the dealer for about $250. I’m going to do the two rear side windows and the hatch for good measure. Is there another source for these that is worth looking at or should I just get them from the dealer?

to be clear, these are the chrome strips with the rubber strip that lays along the bottom of the window glass.
