Hey, there...writing on behalf of my brother, who co-signed for an auto loan for a "friend" who, obviously, isn't much of a friend. The friend made one payment on a $40,000 loan. The vehicle was worth $24,000, but the lender allowed two previous leases to be rolled into this one, thus the $40,000. The vehicle has been repossessed and sold; the remaining balance is $19,000. While my brother understood what he was signing, he is learning disabled (has been since a young child) and didn't understand the potential problems for co-signing.
