the best cart in this budget would be margalla, mehran is very good car if you do not need luxury, comfort etc. it is meant for cheap cost, maintenance, but it can reach up to naran, kaghan, babusar top, even if you are climbing to moon, the first thing you will see there will be mehran sitting somewhere. personally, whereever i have gone in northern areas, even the toughest ones, mehran is the first thing i see there.
