I went through the same struggle... I thought for sure I would not get a Tesla unless it was a P. But I also wanted the 100D.... well, it turns out that the difference in price between my configuration in a 100D and a P100D in which I only get Launch/Ludicrious and red brake calipers, was about $35,000. Are you f*ing kidding me? So I ended up with the 100D, 4.2s 0-60, and I am totally happy. My friend who has the P85D with Ludicrous is jealous, and says the feature is pretty useless for him. I'd love to show off the LM for sure, but as it is priced now, it is a pure vanity feature. For you with the P100D, congrats... big hunk o change for the little red P.
