I am no longer hopeful that the Model ≡ will be shown in multiple configurations. I believe they will eventually come, of course... But I expect the car shown on March 31, 2016 will be a Sedan.
I'm sure the Model ≡ Sedan will be an awesome car that I would personally like a lot. However, I don't particularly like Sedans, in general. If I enjoyed sitting in a car like a preying mantis with my legs bent up to my shoulders behind the steering wheel, I'd probably like Sedans. Unfortunately, I don't find that seating positing particularly comfortable. And, with the advent of increased crash test requirements since the early 1990s, the B-Pillar in Sedans has steadily gotten larger, wider, and thicker than every before. For someone that needs to stretch his legs in the drivers' seat, the B-Pillar in a Sedan is immediately in the way when attempting to make safe lane changes -- SIGNAL, MIRROR, OVER-THE-SHOULDER, GO! I have to lean forward, lean backward, crane my neck, hope like heck I didn't miss someone else's signal in the blindspot, then change lanes. It is a real pain in the [BUM].
That can be avoided a bit by driving a Coupe. Typically a Coupe has longer doors, so the B-Pillar is moved further back, leaving a clear view of my surroundings when looking over my shoulder. A quick glance, without any acrobatics, and I can change lanes, unmolested. So, I'm hoping that there will be a Model ≡ Coupe -- with Falcon Wing Doors -- so that I can be safe on the road at all times. I understand that most people don't have these concerns and buy Sedans by default -- when they aren't getting Pickups, SUVs, and Crossovers instead. Thus, it is very likely that I will have to wait to get a Coupe from Tesla Motors. Though I hope for a Model ≡ P120D Coupe, I could settle for a Model S P135D Coupe instead. Whichever arrives first, I'll buy it.
