All of these indicators show that automotive industry is restoring and tends to expand so spare parts which are complement products of car tend to grow also.
Normally, cars contain 20,000 – 30,000 of auto parts. All of the auto parts can categorize into 3 categories. First of all, “Made-From-Iron auto part” is the engine and body parts. The second, “Electronic part” is circuit part. The last one is “other auto part” which is made from rubber, plastic and mirror. Spare Part Industry tends to get higher growth rate than automotive industry because customers keen on decorating and repairing their own cars instead of buying new one. The important factor for the sales revenue is the useful life and depreciation rate. Because spare part is car complement product so the more useful life it has the more spare parts it needs.
