$12,000 with over 90k and low 4WD drive doesn't stay in? If you have a $12,000 budget you could have a good one tomorrow just through this group. And since you are in NC, just buy a one way ticket and fly there and enjoy the ride back even if it was California. Just be sure the vehicle has passed your inspection. Through this group I would trust pretty much most in what they claim selling their VX. I did mine through ebay and flew to Arizona. The vehicle was in better than I thought condition. Good luck.
From Unimog to VX - a serious change in velocity - a small sacrifice in voracity.
