Hope OP gets his issues sorted out.
With high expectations often come great disappointments.
Point many are making is that lots of Tesla come out great. Some have issues. That is kind of the luck of the draw.
Many are not obsesses with panel fittment and paint purity. They enjoy the car just as it is delivered.
Currently buying a Tesla with expectations of great panel fittment and flawless paint is perhaps setting yourself up for failure.
For many of the same reasons, a person shopping for a Cadillac Escalade should not come to their forums and complain, with great emotion, that the car runs on smelly gasoline and they cannot refill inside their garage. Even a much less expensive can do that easily
If a little upstart tech company can produce cars like that, why cannot mammoth Cadillac do it, even after 100 years.
PS. A close inspection of Cadillac Escalades also can reveal paint issues, exposed poor welds, interior door hinges without paint and needing many trips to the shop over the first few years. Panel gaps are worse than Porsche, fuel economy is criminal, insurance is high, and dealerships don't fix flat tires for free
