2. bear the handling fee. As long as customers are willing to bear the handling fee, I believe 4S stores are very willing to let them swipe their credit cards.
3. Cash installment by credit card. If 4S stores really don't want customers to swipe their credit cards, cardholders can get cash by credit card installment and then buy a car, but the price is still relatively high, which is much more expensive than the handling fee for swiping credit cards.
