To be honest, I'm not sure if you're being sarcastic or serious. I'm guessing serious?

I don't think it would be unusual for them to make a statement that while technically true is misleading.

The number of unique Model S body frames is not a forward looking statement by any reasonable definition.

No, the claim about future Model 3 production may be forward looking, but the claim about the number of Model S body frames that do (not will in the future) exist and the comparison to the number of Model 3 frames that exist doesn't magically become forward-looking because it supports a forward looking claim.

I’m not a lawyer, but I doubt many statements in the past tense would fall under the “forward looking” umbrella.
