i would not suggest indus corolla as you will never end up buying a worthy car as no satisfied owner sells his indus...
vitz too are very abused esp the lots imported back in 2006..a cousin have one on petrol and what he says is that its an excellent car but very high on maintenance! also, petrol consumption is not too good.also, it will not be a car with trunk..
baleno/liana could be a good choice. you will get cleanest cars in this range, manufactured in paki, widely available parts and always support of 3s. there are absolutely no issues with ignition coils ..i have liana 2006 with 115000km on odo, still going perfect with ff ignition coils...both have coils over plug setup...liana is twin cam with timing chain (not belt) and distributorless ignition system..much able to withstand abuses . liana and baleno both comes with ff immobilizer..means almost impossible to steal..
cultus efi/carby will be an excellent choice too but same thing - without diggy and very light body..
