What protection do you think a bank will provide you!? They only know you who will be on the hook once you sign their finance agreement. They probably won’t care what happens to the dealership once they have you financed for the loan. If you think the bank will help you if the dealer goes bankrupt, you’ve got a lot more research to do! As many others have said, use a credit card for a deposit and do a thorough PDI before giving any other money. Other dealers can do any warranty work if needed. And you’re better off doing any minor repairs yourself. Good luck
