Just curious if anyone has swapped their interior trim...instructions on how to do this or cost from the dealer? Also any impact to the inside LED lighting (assume not) since the sizes are probably all the same. I’m looking to swap the matte wood for either carbon fiber or the black aluminum trim. Found I can buy them online, just curious if I can do this myself and how big of a pain it is. Did my old 10 Gen 2 CTS and wasn’t bad but curious on the Gen 3 model.
