Range Rovers are hell to maintain.
Our Range Rover (2006,Vogue,V8) uses about 50k in monthly maintenance,not to mention if you need to replace the tires (80k per tire,and only available in pairs).
Plus,its not exactly cheap and does not fit the 6-10 Million PKR Budget you have set (if you want a new one),a used one is a different ballgame however I would be careful buying used as most owners tend to not take care of their Range Rovers.
