What are your requirements? Hatchback or sedan? Local or imported? CNG or Petrol? Maintenance issue or not? Year of manufacture important or not? Major travel on highways or more urban travel?
You can start form a 82 corolla/90 sunny to Khybers to Margallas to Lancers, old and battered civics, charades and two door low resale altos.
In that price, I personally will go for a Starlet.
