I order the M3P the day it was available and didn't go with the upgrade package. At that point all info I could get was the upgrade package include the bigger wheels/tires, the red calipers (no info if they were more than painted) and a rear spoiler. I thought that was too little for $5K.. I don't really like the wheels (what I really want are the pinwheels that were on the red proto at the reveal and that Elon had said would be available soon). There was rumor that there would be a track mode and I figured I would add updates as I went along. Now I hear that track mode won't be for the cars without the upgrade!
VERY annoyed. So I also hear there will be a path to upgrade but how much?
