Working out the price of the car after ascertaining how the client wishes to pay

Q: I am a car dealer. I am not involved in finance. However, I accept different forms of payment, such as cash, EFT and via a card machine. Is it permissible for me to decide the price of a vehicle depending on the customer’s form of payment? The bank charges me 3,25% (for a credit card) and 1,75% (for a debit card) of the total amount if the card machine is used. Can I add this percentage onto the original price of the vehicle? If so, does it have to be the exact amount the bank charges me or can I round off or add to the amount as I desire?
