I'm on the Aptera list, too. Around #900, the last time I looked. I feel no pressure to change as the i3 REX is a good fit for my needs, so the Aptera can come when it comes. I'm not quite at eNate's level for transporting stuff (that's a great thread, BTW!), but my car needs to hold a regular road bicycle. This rules out most sedans.
And then there's the look. A few days ago, I was in traffic looking at a Tesla 3 in front and another to the left, a Y to the right. W-A-Y too common these days to interest me, and the styling is minimalist (OK, it's boring). I like how Doug Demuro described the facelifted model - The Greatest Appliance Ever Made.
Even if I get a replacement, I'll probably give the i3 to my son-in-law to keep it in the family - he's still running my old '06 Civic with ~150k on the clock, and it's getting tired. He takes personal pride in not running anything younger than 10 years old, so my '14 is just coming into his "acceptable" range!
