No because they’d do it like they always do; ‘Oh, and by the way as of last week all Model Ss have such and such new interior’. They wouldn’t announce a new interior is coming in 6 months. They aren’t stupid. They’ll announce it if/when they are ready to put it in cars now/as of yesterday.
AFAIK Tesla doesn’t operate like all other manufacturers and has yet to specifically discount the current model before a new model steps in. IN FACT, Tesla continuously changes their cars, changes the options available, and routinely does NOT give customers a heads up in many cases.
Just read this forum and find hundreds of posts by members; ‘If only I’d known Tesla was going to change such and such a feature I’d have waited and not ordered.’
It’s academic because it’s not applicable.
