Maybe not all.
Oh definitely not all. But many do. Speaking of BMW paint...
We are wrapping up on a full-monty 2018 Competition Package BMW M4 that is brand new right now. The car came to us completely swirled up and the front bumper got a horrible respray. The respray was likely performed at port or the dealership because I would NEVER think BMW would be okay with what came to us.
I have seen plenty 6-figure cars with missing clear coat on exposed areas, base coat that was not sprayed as good as it should have been and other odd quirks. My .02 is that this is due to an ongoing trend of manufacturers corner cutting to save $ on the painting process. But I've seen, just about across the board, that the coverage and fit and finish of modern paints have taken a turn for the worse over the last 10 years.
