I have a reservation for the M3, and can't wait to get the car. I think the MS is a great car, but frankly I don't need anything that big or expensive. My plan was to get a lot (not all) options on the M3. Biggest Battery, leather, pano roof, dual motor, AP, premium interior, premium metallic paint, 72A charger. Don't want: Bigger wheels, premium audio, ludicrous mode, air suspension. My question is, what's the best guess for Tesla limiting features/upgrades/battery on the M3 to not cannibalize MS sales? If Tesla offered nearly every feature of the MS on the M3, then the audience for the MS would shrink to just those that want a bigger car or more seating.
