HELP: 1997 Corolla with carburetor

I live in Jeddah and thinking of buying a 97 Corolla, carburetor driven; 165K miles. Need help on reliability of carburetor driven corollas; the MPG. Engine is 1.3L manual driven. Bought it to take it to Ethiopia. Easy to get parts in Ethiopia. What MPG or kilos per liter will I get from this corolla. Petrol is expensive in Ethiopia

I am retired and don't have much money. Your ideas and suggestions will be appreciated.
