Tesla did something similar in the beginning. I was early Model S and Model X owner, and at that time Tesla prioritized S/X owners for the Model 3, which I reserved and took fairly early delivery (VIN 3,000-ish).
Thanks! I was just providing time/date data point info for everyone. The tech that delivered it was surprised and said he had never seen it before. I myself didn’t even know there was an old vs new kit. Just happy to have the spare now.
