[Resolved]  Hyundai Santro — Cost of the Plastic Items

The Cost of the palstic items are too high in the Santro showrooms. Bidding of My Back Car door was breaked due to the locks. I tried 3-4 showrooms and they are saying that the one bidding is of approx 1000 rupees & if i don't take this them water makes the door bad because it has the holes for the bidding locks. Now just tell me for one bidding it is 1000 rs. why? is hyundai unsing speacial material for making these tsmall hings & when company knows all these things then why they are making items like this . when they knows without this the product gets damaged.
