For example: If a headlight was damaged, the assembly had to be replace which was quite an expensive deal. Hence, it became important to remind the auto companies to tell, that if they did not supply child parts the cost of the repair would rise because the premium of the same could increase. However, now in case of a dent in a four-year old car, the owner has to bear half the cost due to depreciation. In addition, if the dealer had high-tech dent equipment, repairs on the same could be made at a fraction of the cost.
To make auto manufacturers aware, many private companies are now using the data and encouraging the manufacturers to introduce child parts to bring down the costs. In fact, there have been constant attempts to standardise the cost of parts and labour.
