I don't doubt what you say and agree with you that the software updates are usually great.
Maybe I have a car that was built on a Friday. Funny thing is one time I had my car in the service center when they still used to give loaners. I got another MX, same year, same feature set, wheels and tires, and it road much smoother and quieter than my own car. I even measured the tire pressure (was the same). The only difference was that this MX had 70K miles on it (and mine had 15K at the time). Why in the heck would there be such a vast difference between two cars of the same model year?
I was just out running errands today in my MX and, though I usually have music or a podcast on, I felt like some silence. But I forgot - can't get that in my MX. Squeaks and creaks and rattles galore. When I turned in my Q5 with 30K miles on it it was as quiet and solid - not a rattle or squeak to be found. Shutting the door on a German car is a completely different experience then the Tesla (though I do like that my MX shuts the door for me).
I think it's pretty clear that Tesla cut a lot of corners for margins and to reduce weight. For chrissakes, the thinness of the carpet in my MX is surprising and very disappointing. Bought some $300 mats hoping for a small difference but I think the car would need to be taken apart, have proper sound deadening put in the floor pan, in the frunk hood, and in the doors before any noticeable difference could be discerned.
I should also note, I live in commie California where the streets and roads are falling apart. Perhaps if I lived in Phoenix or some other city where the asphalt is buttery smooth then maybe, just maybe, I wouldn't notice some of my car's shortcomings. In any event, looking at the 2023 Audi E-tron GT.
