Is it permissible to sell a car that was purchased in installments through an interest-based bank, and is it permissible to benefit from its price?

If the usurious bank purchases the car for you in a valid transaction, and it comes into its possession, then a sales contract is concluded between you and the bank, the contract is valid, and you own the car. But if it does not purchase it in a valid transaction, then it is a corrupt usurious loan, and you must return the principal and repent from engaging in usury.
