My dealer says yes. The factory rep said yes. Although he seemed to suggest one day it will come back. I went ahead and got a new one just in case.

 

Have not seen any messaging from Lexus on this but would not be surprised due to the current consumer trends to SUVs and away from sedans.
They did discontinue the GS350 in 2020 and not sure they have any regrets. More regrets from the diehard Lexus enthusiast.

 

Just bring back the LS430 body and chassis and refine it with modern electronics and safety features.

 

I haven't heard anything. When the GS was discontinued, it got a lot of discussion around here before it was officially announced.
