I can attest to low ball trade offers lmfao it was so bad. They offered me 45k for a 2016 p90d w 5k miles. Lololololololololwhile i do agree the cars aren't always perfect, you can't single out Tesla. Look at McLaren build quality and you can make the same argument (it's pretty bad).
i'm here to support Tesla. i've been a long term shareholder and i want the company to succeed. yes, it's really frustrating to see these defects, but TSLA made me a fortune so I can't complain too much.
As for Tesla low-balling your trade-in... simply don't accept it and sell it privately. That is what i did with my 21' Model S refresh.
