I'm waiting for the identification of the "something special for line-waiters" from Elon, along with dual motors. The "something special" would presumably be a configuration option (hence no postage or fulfillment costs and headaches).
Other than those two features, what would be nice to have? A non-black interior for sure, although the black headliner is the only way to go imo but the rest of it? Yeah, lighten it up. Then again, that's not hard to get done aftermarket.
Otherwise, aside from the stuff for which we're all waiting (360-degree view, in-car hotspot, camera stalks instead of side mirrors), the range is already decent and the car moves down the road without things falling off. Sounds like a pretty good deal to me. Hey, I'm easy.
