Why on earth do you think that’s the case? They’re selling something, they’re not in one of the limited industries where you have limited rights to refuse, and method of payment isn’t one of the reasons you can’t refuse to do business with someone. A handful of places prohibit not accepting cash, but it’s not enough that I would assume that’s where they were, particularly if a business opted to just casually refuse.
You are correct. What they can’t do though is only allow you to buy the car with one method of payment, which is what is being described here.
