As you are in islamabad so in your budget only margalla suits you. Recently my neighbour sold a black 97 margalla for 490 it was in original paint but was faded so you can guess the true price of clean and trouble free margalla in isloo these days. Rest forget about baleno and city. Baleno starts from 600k and that too 2001-2002 model in good condition whereas city 2000-2003 model starts from 700k-800k good condition
