I never said there weren't other priorities. I was adding to Dan's post which stated those. Location has definitely been one of the first factors and especially high marging builds. But I guarantee that within those categories that ownership will be a big factor as well. And this has nothing to do with wanting to be special. I'm just referring to the Model 3 experience. I stood in line to order it but saw plenty of Johnny come lately's get their Model 3 before me because they owned Model S or X's.
There is some rationale for this. Existing owners are more likely to be tolerant of early production issues, they know how to engage w/ Service to get their issues resolved, are more patient w/ Service, etc. There are tons of threads on this board from people for whom M3/Y was their first Tesla, the most expensive car they've ever purchased, it's having issues, Service can't see them for 2 weeks, this is our only car, Tesla sucks, yadda, yadda.
IMO, Tesla will build and ship whatever configurations are the easiest to build so they can show a quick ramp. We can speculate on what that config is once they launch the configurator, but it may be a certain option combination that Tesla Manufacturing determines is the simplest to build. All else being equal, they also prefer higher margin but with their recent cash raises, I think that part is less important than it was in the S/X days when they needed cash. I think showing high production and delivery numbers will trump all, so they will build the simplest configs first and for those who to whom they can deliver the quickest.
