Also the newer parts seem mostly interchangeable. Daerik via youtube upgraded his side cameras on his MX, they were plug and play. I'm pretty sure there'll be an easy cable solution for the USB C upgrade coming from a vendor in China soon too.One of the Elephants in the room ( for those of us not leasing ) is depreciation. At the moment the Model 3 is looking quite promising though until they start to hit the used market in volume the numbers will be distorted. I imagine the Ipace is a disaster for anyone who paid close to list. I wonder how the likes of Etron and Polestar will fair.
The OTA updates are allegedly good in this respect since a 3 year old M3 will have pretty much the same functionality as a brand new one.
