I would theoretically be quite happy with the LX600, except that the current LX570 is clearly less off-road oriented (even if the underlying car is the same) and extremely ugly (imo) compared to the LC200 and I don't expect that to change for the new gen. Honestly was mostly interested in the GR/Sport version of the LC300 because of the off-road orientation and stripped-down look.
I suppose if there is no LC300 in the US, there might be a version of the LX600 that is off-road oriented. This
video claims that the F-Sport LX600 may be similar to the GR LC300, so I am holding my breath!
