Is it permissible to buy a car where immediate payment is at one price, and payment in installments over 12 months is with a 10% increase, and over 24 months is with a 20% increase?

If the company owns the car, it is permissible to sell it for immediate payment or deferred payment in installments, even if the deferred price is higher. The conditions for this are: specifying the price in the contract, specifying the number and amount of installments in case of deferment, and ensuring that the price does not increase due to late payment or the imposition of a penalty. However, if there is an intermediary, it is a condition that the car first enters into his ownership and responsibility.
