We will submit your financial paperwork once the 7 day post purchase return window has past (Please note that if you are registering your car out of state, the 7 day return window is not applicable). Lenders will process your financing information typically within 20 business days at which point they'll reach out to set up payments.
If that time has passed, we'd recommend first getting in contact with your selected lender as they will be able to speak to the details of your payments and loan.
