Think it makes sense now. The $20k Solstice will be stick only. That is the base model. For a few shekels more you can get the ->Sport Edition<- with even more badges, different paint, and a paddle-shift automatic (Pontiac did the same thing with the Fiero in 1984, if you look at the original sales brochure - GM4468 inside back cover - the base Fiero was not available with an automatic, you had to move up to the Fiero Sport or Fiero SE).
So Pontiac can say with a straight face "On introduction, the Solstice will be available with five speed only." (to get an automatic, you need the Solstice SE).
