Moving overseas, should I keep or sell car?

Moving overseas for the next 4 years... got a 2006 Grand Vitara with every option, including RetailRed paint. Trade in value is just under 11 (KBB) and I owe 17, if I maintain regular payments of 395/mo. We love the car, so here are my options as I see them: keep it and come back to a nice, fairly new paid off car; sell it and take it in the shorts; keep it until i leave, then have someone sell it for me... what do you guys think?
