After 8 years after your car was repo you are being sued i did not receive a letter after repo?

Did you borrow the money and sign a contract to repay the loan? Did you have your car repossessed because you failed to make your payments? They repossessed your car and sold it, and you owe the difference in what the car sold for and the balance on the loan. What difference does a letter or 8 years make. Be an honorable honest person. Pay them their money. Legally you may get out of paying but morally you owe them the money you borrowed.
