I think the magic combo to get priority build status will be the larger battery, dual-motor, with Autopilot combination. I don't think the Performance version, assuming there is one, will be the first type off the line. My reasoning is that Tesla will want to stay on message with electric for the masses, and this combination will most likely be the most popular version. Just pumping out $60,000 P versions for the first several months would be antithetical to the 3's mission, and could potentially be a PR nightmare. Looking at the stats on Model3tracker.org, over 80% of reservationists in it's data set have said that combination is what they want. So, my not-so-educated guess is that is what we'll see first, then after a few months we'll see base cars and P cars worked in as well. So fun to speculate, huh!?
