I got somewhat different information from my Lexus dealer in Michigan.
They claim the first production run will have two versions:
Option 1 has a Sticker Price of $52,545.00 including freight. It's fully loaded and the included options are:
EY (Rear seat entertainment)
HS ( Heated front seats)
ML (Mark Levinson)
Option 2 has a sticker price of $50,705.00 also including the freight but no EY option.
For the first run, they are building a total of 434 units. Out of those, 391 are option 2, and 43 are option 1. This is the total shipments for the Chicago region in the first month.
Perhaps there are regional differences.
