OK...that's a (not so) minor detail you left out.
I'm starting to understand. So she listed her car with
TRED, is that right? But now she's confused about how it works?
TRED actually sounds like good/safe deal for
both of you.
You pay TRED $6K for the car.
TRED pays off the loan for $6500 and gets the title.
TRED bills her $500 to make up the difference between the loan amount and sale price.
TRED sends you the title to the car.
It's too bad she's freaked out about the process. Vroom and Carvanna work in a similar way.
Why don't you get a loan through TRED and then pay it off after she is out of the picture? Or is she so freaked out by TRED she doesn't want to use them any more?
