I am confused about the "Textile seating"! I understand these are cloth seats and that there is vegan leather available to choose. I don't specifically see in the premium options list where that upgrade is. Premium Upgrades Package – $5,000 Upgraded interior with additional features and premium materials.Premium heated seating and cabin materials throughout, including open pore wood décor and two rear USBs12-way, power adjustable front seats, steering column and side mirrors, with custom driver profilesPremium audio system with more power, tweeters, surround speakers and subwooferTinted glass roof with ultraviolet and infrared protectionAuto dimming, power folding, heated side mirrorsLED fog lampsCenter console with covered storage and docking for two smartphonesNowhere in that list do I see upgrade option for seats; at least not specifically. I know the Vegan seats were a big deal last week, so I imagine they are only available in the Premium Uprades Package. Or is a separate price not yet listed?
