First, love the information here on the Forum. I have an earlier (~3500) production Model X 90D. I love the car and have had very little issues with it. But the new battery will pretty much get me everywhere I need to go 90% of the time. We have family 260 flat interstate miles away and the 90D has to stop to Supercharge. The enhanced auto pilot is also pretty amazing. Taking cost and loss on the 90D out of the picture: 1. Is the upgrade now the right time to do it, maybe getting the tax credit still (early April delivery)? 2. Is there a body change coming as per so internet rumors to the Model X? 3. I am missing anything? I want this to be a longer time own and before my new order goes hard thought I would ask the experts out there. Thank you.
