There are already whispers that the 86 is the next model to receive this performance trim. I doubt that Toyota will ever offer the Century outside of its home country, but it is a great looking car.
I heard that the GRMN Century seen here was a one-off build for the brands CEO, Akio Toyoda, with no mention of it going to production.
With the new LS here, it sort of fills the spot a Century would have, so don't expect it at all. In all its decades, the Century has been Japan-exclusive.
