Took my MS in for service was given a New MS P100D. Noticed there was no badge on it then when I looked under "about this Tesla" this is what came up - thought it was pretty interesting. You can drive one MS and compare it to how other MS would drive. Still curious as to why no badge? Would they make all MS come with the same battery then if you wanted to upgrade from a 75 to say a 100 you could just upgrade like they were doing with the 60 to the 75? Interesting thought. Would explain why no badge. Or is this simply a demo car so as to not need all the different models for test drives?
