We may have different interpretations to defend or criticize but, at the end of the day, it is a car with poor assembly of trims.
Tesla is a good car in terms of technology, maintenance cost and many other things to be proud of;
In fact, in my opinion, Tesla is a very good software and energy company; but, in terms of fit and finish, Tesla cars are ordinary and cheap.
It doesn't matter what year it is build and if you purchase a Model S or Model Y. The dashboard, interior plastic materials, rattling panels and trims, assembly of the product, industrial design etc etc. There are plenty of opportunities.
When you spray windshield fluid, it floods your car. It is a design failure! The Center console does not provide enough leg space. Doors are misaligned (compare that with Mercedes). Paint quality is poor (Compare that with Mazda). Cabin noise and trim assembly is terrible (Compare that with BMW). Trim quality is poor (Compare that with Cadillac)...
But with all that in mind, plenty of people love that car because if you compare the advantages and disadvantages, you may accept the car the way it is.
Tesla can have million reasons for that, but the day that other car companies catch up and -if- a company like Lucid, challenge Tesla with their luxury product, Tesla may improve their own product trim. It is business and market. Supply and Demand. Remember you pay 35k+ for a used Tesla. You can have a used Bimmer with that money.
