I wish they would share the full details of the mentioned Purchase Agreement, but it does not sound like a scalping prevention scenario.

"... he signed a Tesla Vehicle Order Agreement which states if a Cybertruck owner sells the EV during the first year, they can be fined $50,000 and be banned from buying future Teslas."

I have never purchased a new vehicle so this is out of my wheelhouse, but the article reads like Tesla does not want people to buy and then dump the vehicle as a way to disrupt sales/reputation of their vehicles.  This may be specific to only Cybertrucks and not all new Teslas.

Regardless its suss af, not going to buy a Tesla.
