If you are going to buy daewoo then buy one with best condition engine nd interior vise . It is costly to arrange things after purchase. You better pay once for good car otherwise you will regret it. Market is full of woos ranging from 80k to 350k. A well kept will be above 220k.
As for engine, its stock engine is best and very simply even you can repair everything by yourself if you have technical know how. Buy this car if your city has spareparts . Like in twin citiies,Lahore, karachi parts are easily available. We have a whole thread here search dfc ( daewoo fan club) on pakwheels.
