Toyota's most luxurious vehicles in the Americas and Europe are part of the Lexus line, but in Japan, that title belongs to the Toyota Century (not related to the Buick Century). Seeing as how famous Japanese GTA player Mas Chan has actually created a video on a custom Century (whilst drifting, that video is here:), I scoured the web for an available mod for an installation of the Toyota Century, to no avail.
Alas, I have found a Century from GTA IV that I believe deems fit for being put into GTA V; https://www.gtaall.com/gta-4/cars/86111-toyota-century-2005.html
I do believe that the Century deserves a part in the GTA V mod community as it does in real life. Maybe as a replace vehicle for the Washington or the Emperor. Thanks for reviewing my suggestion.
