You didn't state your price range, which would be appropriate for any piece of advice. However, when it comes to Daewoo Race, I would give it a thumbs down. Parts would be an issue, plus most mechanic would not entertain you if it malfunctioned or required any repairing.
If your budget is as low as PKR 150,000, increase your range and go for Mehran (I never thought I would ever advise anyone to buy it). If your range is above 300k, then you would have better options such as Margalla, Cuore or if you get lucky, 86 Corolla (Khyber is a good car but has the same problem of availability of parts.
See, because I don't know what your price range is, there are too many ifs and buts. But say NO to Daewoo Racer.
