Brother, thank you for the advice. I'm sorry to have disappointed you with my "childish" question. I asked because I'm not a Karachi-ite and not familiar with people here. Also, I never had time to indulge in engine installations or spending time with mechanics ... my father isn't a feudal or "sarkari afsar" making blind money like many in Pakistan. I worked hard to become a doctor and earned enough to fulfil my childhood dreams of driving a Pajero.
So, brother, please, instead of hastily judging others, be understanding, kind, and caring enough to keep your thoughts to yourself when they don't intend to help others.
