Yes very expensive compared to Civic but again, it's a Mercedes, parts are bound to be expensive. If you do not want to spend alot, then prefer using the old original parts which you took off after facelifting it. If you require new facelift parts, prices of parts for these will be inevitably expensive in cities such as Lahore, ISB, Karachi or Peshawar so prefer going to yards near Quetta or Swat as another member also suggested, maybe you can find for cheaper prices over there. By looking at the picture, bumper can be repaired. Just needs new bonnet and grill, is the right headlight fine or just left one damaged?
