From real life experience...
In OH, I have a friend that financed a van. The engine went out and he left it parked for a few years, making payments until he could not afford to and stopped. When they came to repo it and saw it dirty, wrecked, on 2 flat tires, they left it also. Called him religiously for 6 months trying to negotiate a discounted price, like was done with you. He told them he was disabled and couldn't even support his family with what the household had coming in. The van sits..... the loan awaits... for years. I hope your cosigner likes you, if they are collectible still.
