Sold car now being threatened for civil suit

[Carissues az]

My daughter had my 2006 ford escape in colorado that had a lien on it and i was still paying on in az.
She wanted to sell it to someone she worked with for less than the lien. I advised my daughter that that was not the deal and after looking at KKB value the car was worth $2300 in fair condition and that she needed to tell tgr buyer I was not selling it for less than $1800.
I also did not promise to pay any repair costs but my daughter said she felt bad I had raised the price and stated she would repair the window in a text message to the buyer. This sale was not between her and them, it was a vehicle in my name and I did not agree to this.
The bill of sale that was notorized by a bank stated no such repair agreements and that after they paid the 1800 iI would send them the title, which I did immediately after the bank released the lien which was in about 2 days.

Now the couple is threatening to take my daughter to civil court because she has not paid for the repairs. Is this something I or my daughter need to pay for if the car was in my name and she had no authority to make those promises?

What responses should I make to the couple?

She had the authority..She was acting as your agent in the sale.
