My brother is looking to get a car but dealerships here use interest.They’re giving my brother an offer where he doesn’t have to pay interest but they increase the cars price by what they estimate they would’ve profited off the interest. So a 20,000 would be 27,000 but with no interest.Is it allowed

It is allowed to buy at a higher price on installments.
