In domestic market, the major competitors are Nissan, Honda and Suzuki while in international market, there are more competitors such as Ford, BMW, Volvo and Benz.
In future, I should say the majot competitors are Korean car producers such as Hyundai, Kia, GM Daewoo, Ssangyoung & Samsung and China car producers such as Sinotruck and Changan Auto. The reasons are that those are recent set-up automobiles firms and they are competing for the developing Asian countries.
