Tesla said it would deliver my car in February / March. It has now had six extra months to address any unexpected “part shortage” related to white seats. If they don’t deliver my car in October, I am suing. As far as I am concerned, they are scumbags and it is time to set them straight.
It would be a very tough case and probably not worth your money or time. But if you are a lawyer or know one that will do it just to be an irritation to Tesla, I suppose you could. For your mental sanity it's probably not worth it though.
