Well, you even said it yourself...the other user’s (ONE person) experience is based on nothing....because it was apparently an opinion made even BEFORE Heritage Edition came out. Why do you keep repeating that as a “source” To your claim? How does one come to a conclusion on leather durability on a car that has NOT come out yet at the time of opinion?? LOL
Have you seen some of the leather conditions on USED LCs from before 2016? They are not that pretty. Somehow you think that semi-aniline is less durable.
And we don’t even know if Heritage Ed has the same leather as pre-2016 leather! Where do you get this info from?
KDSS bolt is an upgrade to an area that clearly had issue. I am not sure if there is a solution to that issue...i am not car engineer. BUT, again, how do you know that the change in KDSS bolt won’t work?? Has there been a 2018+ LC‘s KDSS bolt that has corroded to dust like previous years?
Why do you love to make these kinds of leap of faith conclusions?
