-1 get a new passport
-2 enter KZ overland this time by a road border (so you have a car stamp in your passport - car means you entered by road, not necessarily with your own car.
-3 Get out of KZ to either Kyrgyzstan or Uzbekistan. At the border say you are an idiot, very careless, and have lost the paper they gave you when you entered the country this time around. Hope they don't have a computer system. Have all your ownership documents which show you have owned the car for ages, and if they pick up that you entered with the car two years ago, say there must be a mistake, you have owned the car for ages, and that of course you came with it to KZ this time around. It could easily happen that you car was not entered correctly on some database somewhere.
-4 IF you get past this, then come back into KZ, re-enter the RUS - BY - KZ customs zone and get three months
-5 Drive home
