My wife and I took delivery of a model Y performance with performance upgrade in midnight silver metallic in late March. It's our first Tesla and we love it. It was darn near perfect, there was some paint missing on the hinges for the lift gate that the Fremont Delivery Center fixed, and we have a loud noise from the heat pump using the AC -- mobile service is going to install a foam noise shroud in a week, other than that no fit and finish issues. We just joined TMC but we've had the MY since late March. As such, it has a low VIN # (<400) so we were worried, but we found no panel gaps, squeaks, or other paint issues.
