Thanks, mia. I've followed those threads in the past, since we're interested in putting the whole amount on the card and would be willing to cover the finance charge. But what I meant was, under the Amex Auto Program is it required to pay with an enrolled Amex card?
Not sure exactly what you're asking. Are you referring to the need to have a Cent card and the Cent program or just the Amex Auto program?
With the Amex program you don't need to "enroll" in anything or use an Amex card at all for the purchase.
