This guy (Sandy Munro) owns a company that does tear down analysis for a lot of manufacturers. He's done a bunch of videos on Teslas and has actually become a huge fan (his initial analysis of the model 3 several years ago was "built like a kia from the 90s"). He interviewed Musk a couple weeks ago was well.
Here's his latest series on the current Model 3. Seems they've made some good improvements over the past 2 years but he is still mystified as to why they continue to struggle with exterior fit/finish. Interior is near perfect. Really interesting stuff if you watch the whole series. Love the little zingers he throws in occasionally.
