I just charged the 3K downpayment for my Accord lease. Dealer didnt wanna take the CC at first but since it was the holiday weekend (12/26) I said no banks were open (they wanted a bank check) and well how bad do they want the sale before the end of the year, since I was going away on the 27th til 30th.
They did not take AmEx though. They get charged 4% using Amex. They only accepted Master and Visa.. so i went with my Amazon card...
