[OCONUS MOVE] just bought a new car what should we do about the lease?

Good afternoon:

 

We purchased a new car last August, but now I am being stationed in Japan. This is my first PCS so yes I probably should've know better. C'est la vie. 

 

Now I just need to know what the best course of action is to sell the car so we lose the least amount of money. Do we go through the dealership or try to find a buyer privately.

 

We've paid almost $10k into the $36k car. Thanks for any advice!
