Is there a bank that allows a cosigner for a car not be related ?

The co signer will be on the title, that you won`t get until it`s paid off. Prior to that, the bank is the leinholder.You don`t say whether you are an adult or not. But, it`s my understanding that if you have someone willing to co- sign, most dealerships will do it (if you don`t have bad credit). and if you tell them you are related, how they gonna know you aren`t?I have different last name than my youngest bro. cuz he has a different Dad.
