The LX/Landcruiser, never. That’s been a Toyota staple for over half a century. The RX-L will not come anywhere close to the size or capability of the LX or even the GX. It’s not a volume seller but they make lots for every one sold.
The interior has been updated to match the other Lexus models as with the exterior. That’s all they need to do with those two for the time being. Why mess with a good thing?
