I have a 12C but I don't remember how to use it for this query.

No, I'm not getting a car. Someone asked if I was interested in taking over an existing loan. What I noted in the OP is all they could remember. They couldn't remember the rate or financed amount. Sounds like one of those 'how do I get out of this room' puzzles. I should be able to figure it out more quickly than using Excel.
