Hi all, I've got an order in for an S90D, configured with Next Gen seats and premium package. The Design Studio for Canada was just updated this week and Premium seats (with ventilation, like the Model X) are now available with the S90D. I called my DS and he said that because my order is less than 2 weeks from production, I can't change to the ventilated Premium seats. Questions: 1. Is there any way to "push harder" to get them to include these seats? My car isn't in production yet, so I don't see why they can't change it. 2. Is the change worth the battle? Online reviews for the seat ventilation in model X appear to be mixed (some say it's barely noticeable). Next Gen seats appear to have bigger bolsters and a longer seat base length, which may be better for me than Premium seats (I'm a tall thin guy, 6 feet). Thanks in advance for your advice!
