AnswerI am thinking about consolidating a couple of car loans which are at 6.5% and 7% and paying them off with an American Express credit card which is offering an interest rate of around 3.9% until balance is paid off. Would this be a wise move?: "As long as you make your payments on time with American Express and not give them any reason to cancel the 3.9% interest rate, this could be a good move. But remember, credit card issuers can change terms and conditions on very short notice. A car loan is usually locked in. "
