8.1.3 After considering the relevant provisions of the Act, findings of the DG report, conceptual framework relating to the issues with respect to the “aftermarkets” and “systems market” as concepts of competition law, submissions made by the Opposite Parties and other material placed on record, the Commission accepted the aftermarkets definition as opposed to the concept of unified systems‟ market definition advocated by the Opposite Parties to argue that the sale of cars and spare parts together constitute a single market. The Commission had held that there exist two separate relevant markets: one for manufacture and sale of cars , and another for sale of spare parts . The latter is further divided into two sub-segments, consisting: (a) supply of spare parts, including diagnostic tools, technical manuals, catalogues etc. for the aftermarket usage and (b) provision of aftersale services, including servicing, maintenance and repair services for vehicles . Further the Commission held that a „cluster market‟ exists for all the spare parts for each brand of cars, manufactured by the OEMs, in the Indian automobile market. The Commission rejected the OEM‟s systems market definition primarily on two grounds—firstly, the consumers/buyers in the primary market ( manufacture and sale of cars ) do not undertake (and are not capable of undertaking) whole life cost analysis when buying the automobile in the primary market and secondly, reputation effects do not deter the OEMs from setting supra competitive price for the secondary product. The Commission, relying on the hard reality as depicted by the facts, concluded that in-spite of reputational factors, as argued by the Opposite Parties, each OEM has in practice substantially hiked up the price of the spare parts (usually more than 100% and in certain cases approx 5000%); thereby rebutting the theory that reputational concerns in the primary market usually dissuade the OEM from charging exploitative prices in the aftermarket.
