Brother I think you have used some big words calling Mercedes a DUMBO......yes BMW's are good ONLY when it comes to high performance cars....... but for a basic car like yours, even AUDI makes better cars than BMW's........they only became competitive after buying Land Rover otherwise they were going bankrupt.... well its a big debate as to what really happened as opposed to what did happen...........just a point regarding Mercedes being a DUMBO according to you!!!!!!!!
Secondly......I am in Australia and the same car here is between 35-40 thousand Australian dollars....and considering the taxes in Pakistan for used cars, it wont cost me over 5.5 million..................cars are much cheaper in UK than Australia......so considering everything, I guess price is on the high side and it would not have costed you as much as you claim that it has........but considering how things go in weird ways in Pakistan, you might get someone who would pay you that much....
But in the end........................your car.....your price.....your decision
