Well actually, Mexico and Costa Rica are considered NA as well. It sold (although poorly) for a few years in Saudi Arabia but that ended after MY2017. Cant wait for the new model to be released, along with the LX600 and LX750h.The Sequoia is not NA only.
Your second statement has almost been 100% verified by Toyota themselves. Especially with them moving Sequoia manufacture to the San Antonio plant. And pushing Tacoma manufacture completely to TMMMX.
