Well, open air cars I don't think anyone has done, and that means new tooling needed. See how long that takes if they do decide to do those. Guessing that may be as well for other offerings we have not yet seen.
They could reuse most of the tooling from the current cars (Frame, roof, trucks, majority of the detail parts etc.)
Would just need a new body/ modify the current body. This quickens the turn around time.
