Totally agree...my LC interior is very lackluster. I love LX interior (minus mouse thingy) and the ML audio is to die for! I hate the fake wood in my LC!! Oh well.
I don't think it's "lackluster', you still have semi-aniline leather (though not as nice as LX's semi aniline) and plenty of luxury.
Me personally, I wanted the flagship Lexus truck for all the Lexus goodies. I love the LC name too but LX is one, and it's the best rebadge ever lol. I also own an old LS. Two Lexus flagships.
