I'm old and have bought more than my share of new cars in my lifetime. I have never scrutinized panel gars until I started reading about these issues on the Tesla forums. Could every one of the cars I owned previously been perfect? I supposed so, but I doubt it.
I had a Prius for years and one time I read about the white bumper (plastic) being a little different shade of white than the rest of the car (metal). Sure enough, after looking at it, I could see a slight difference. Not noticeable until I was looking for it.
Certainly, Tesla has its issues, but if you look at anything long enough, you'll start seeing problems (just ask my wife). With thousands of us standing there with a delivery checklist in one hand and a cell phone camera in the other, things will inevitably be found that otherwise would have gone unnoticed.
Hold Tesla accountable for their problems, but if you want perfection, you might be disappointed. I never brought a delivery checklist to a Toyota dealer, but I'm sure if I had, I would have found problems.
