My new - new to me car but it’s second hand - will be ready for me to collect this afternoon. We’ve financed it between savings and a bank loan so when I pay for it, it should be by my debit card. Do I do the whole thing by debit card it is it wise to pay a little on credit card? I remember seeing something about protection when paying by credit card but can’t be sure. The car is through a National dealer if that makes a difference.
