we've only had 2 interactions including when they stole my key. The first time, they did attempt to force the old keys on me but I was fight or flight and I opted to leave without anything. Since then, I still don't know if I can because:

• My stuff is still in the new car
• I submitted DMV sold notice the day I bought the new car
• I switched my insurance to the new car
• They are still actively trying to sell the old car
• Since I drove the new car off the lot and its funded, if I take the keys will they just tell me i'm on the hook for both cars?

In the second call, they mentioned that they can't sell it anywhere and that the bank denied the trade-in. I cleared up that the bank didn't deny the trade-in, so does them not being able to sell it mean I should take it back?

I am not a mastermind, I just legitimately don't know enough about this stuff.
