How do you pay for a car today?

How do you pay a car at the dealership today? That’s what I ask because I have to think about buying my new car 12 years ago. I’m the type who likes cash and I don’t have a problem running around with €2000 or €3000 or from the bank to the dealer. At that time the dealer was just shocked that I had the €14000 in cash with me. He just meant that you don’t do it anymore… Now my question like this is going on today? What next I’ll be like If the merchant doesn’t want the money, he’s in bad luck.
