Great! Thanks for that.I asked the SA at Tysons about the battery drain - he said 1) the cars waiting for the part are stored in a deep hibernation mode that does not drain 1% per day and 2) they are able to charge them if needed, it's not fast and it's not something us non-tesla people can do, but they are keeping track and able to remedy. He told me my car was in the high 60% range, he was able to see it in the computer.
