Bro power windows are not reliable in Mehran i tried but they broke too often so i removed them. In the case of suspension u cant change that in Mehran as well as no other parts are available and for transmission i hate auto as well as it is a brand new car why would anyone change transmission. For sunroof i have to cut the roof which i wont ever why would anyone in a new car. And for the digital meter i tried to find one in sultan ka khu but couldnt but i am still searching for it. But thanks for the suggestions.
