I think some of these questions have quick answers. Some get into subjective territory:
Main changes for the +2016 LC 200's? As compared to pre 2016 model years.
Bigger Brakes?? - I've seen that in various articles, but no official literature from Toyota.
Infotainment - which years...
Long-time Toyota owner here. I've had plenty of experience driving their North American offerings as well as some of the overseas models. Love Toyota's to death and won't consider switching to another brand, even if there might be other options more "practical" for more daily needs.
