International car storage

Hey there,

I kind of need your help. I am travelling with my family on the silk road eastwards with our in Germany registered car. We do have to get back to Germany once we reach Uzbekistan and would love to store our car for 5 months before heading onwards.  Do you guys no if it is possible to leave the country by plane having entered the country by car. Has anyone an idea of a good storage around urgench? Does anyone have any experiences?

Maybe a contact to customs police/ department?

Greetings
