My rep told me while I was at the dealer I could delay it up to 6 months...then no more. I guess they kind of wing it and have some flexibility, but I didn't see any written policy anywhere. I'm basically just going to try and get my current car sold as soon as possible. If/when the Tesla is ready, see how it goes then. Wont' rely on the Bill, but most expect it is coming and will happen, any delivery date this year will qualify. But my biggest issue is selling my current ride and getting some money out of it really.
Thanks
