I was thinking that once they do open up a new option (be it white interior, or AWD) it will create absolute havoc at the factory/delivery logistics. We've had 8-9 batches of invites, each with around 1000-2000 (and over 3000 for the Feb 22 batch), which represent over 17,000 total invites to date (if you believe the estimates in the tracker spreadsheet). And of course a certain percentage of those 17,000 represent deferrals for various reasons. But take any given reason (AWD, white interior, SR, etc.) and make it available, and it's basically like a whole new mega-batch of invites goes out, because the people that deferred already have their invites and were just waiting for that moment. If they wait much longer to introduce these options, time-to-delivery for some people will likely be months if only due to the fact that there might be 6000 people ready to configure an AWD all of a sudden! The only hope they have is to get production rate all the way up to 5K/week, but the longer they wait to offer those options, the worse the problem gets. Kind of stuck between a rock and a hard place.
I was thinking the same thing. But "havoc" is a strong word. Maybe delivery takes an extra month or two. But we'll still get our cars, and configured the way we want.
