What is the ruling on usurious transactions if the bank requests the value of the car in cash from the dealership, then gives the customer a check in the name of the dealership along with an order to transfer the car to his name, and it is directly transferred to the customer's name, knowing that the check was not written in his name?

This transaction is impermissible and not a legitimate murabaha. What is permissible is for the bank to purchase the car and for it to be fully owned by the bank, then for the bank to sell it to you. Its direct registration in your name does not pose a problem. However, if any of these conditions are not met, then the transaction is usurious, and the bank writing the check in the company's name does not change this.
