lemme give u some rough estimate of the cars present in ur wishlist;
spectra (450 to 600 k PKR)
Sunny (480 to 575 k PKR)
Civic 94 (350 to 475k PKR)
Pajero Mini (wont sugest)
Core (300 to 400 k PKR)
Alto (125 to 299 k PKR)
Revo ( wont suggest)
considering ur this very budget, it seems that u r some person with limited resources, i would suggest go for Sunny ( i dont think if u can find 1 but still good luck) or cuore. Have you tried Khyber or cultus or Baleno . well I am a big fan of Baleno. Its not very expensive not very luxurious but ... it a devil in itself.
before buying one, just pop into the driver seat and go for a quick spin.
cheers
