I have a friend that is ridiculously upside down on his car and wants to get out. How?

Buddy bought a new $40k Durango in January 2016. It now has about 45k miles. He likes it, but business is slow and they want to cut expenses. Due to FCA being FCA, his truck lost 50% of value and he’s about $12k under.

He was looking at used cars in the $10-13k range, but So far he can’t find anyone willing to lend 200% of purchase price.

So, short of repossession and deficiency what are his options?
