I am not a fan of the 'my MY' usage either. If I had a Model Y I'd never write MY, but that's me. I don't even like M3 much, but I can call my car the P3D- so that works. This abbreviation requires some explanation to non-Tesla owners and to Tesla owners too, come to think of it. I own one and had to ask initially why these characters were used like this, though I had a rough idea. Performance Dual Motor - PUP (another acronym) which is Performance Upgrade Parts. I've learned a lot just reading through posts and making sense of all the acronyms and initialisms.
Some people use phones and such so I suppose it's a little easier if you're using a tiny virtual keyboard to write M3, MY, etc.
It is imperative that one always list the model S, 3, X, and Y in that order when listing them all.
S3XY!
Do you realize you have an LR in your signature in place of "Long Range"? Why?
