Great paint and tight body panel = great quality, amazing car
Not so great paint and less than perfect body panel alignments = shoddy quality, defective cars, crappy build, piece of junk, would never buy in a million years
Quality of a car = what can be visually seen, like a painting or an art piece.
What goes inside the car, has very little to zero weight age and doesn't factor into the measure of what constitutes quality. So much so, some folks might even consider a shell of car with absolutely nothing under the hood, but with great paint and panels and upholstery, better "quality" than a Tesla with paint chip on the bumper.
Of course that means I am a Tesla lemming and a fanboi.

Tesla has a lot of work to do to catch up to dinosaur legacy auto who has perfected this aspect of car manufacturing by working on it for over 100 years, but it tickles me to no end, on what constitutes the ultimate definition of quality of a car for some people.
