Took home-delivery of a MYP on Saturday, also from the Irvine delivery center. VIN 409,xxx.
Ryzen, lithium-ion 12V, dual pane front glass, and heated windshield. However, it came equipped with Pirelli summer tires instead of Michelin all-seasons. Understandable given my region's mild climate.
Side note: given all the chatter about a rough ride, I'm finding it surprisingly comfortable on all except the worst roads. It's also really quiet inside. My 2018 Model 3 was super loud at highway speeds (road and wind noise), but this car is far more hushed.
