Just because you don't notice issues don't mean there aren't issues. Tesla is widely regarded by "car people," both those who own them and those who don't, as having some of the worst fit and finish of any production car in the US. It's been that way since the Roadster. Here's a video review of the most expensive Tesla you can buy, by someone who rates cars professionally and rates it among the best he's ever driven, with paint flecks on the mirrors and other pretty egregious issues given the price point - https://www.youtube.com/watch?v=qen0ZlZM0ZA - and the video is less than a year old so it's unlikely given the long history of these and similar issues that they've made radical changes to their processes in the last 9 months or so.
