REPUBLIKA.CO.ID, JAKARTA -- The country's largest car maker PT Astra Internasional expresses doubt that sales of automotive products would increase in 2016.

Car and motorcycle sales would not increase under the economic slowdown, Astra's investor relation officer Ira Ardianti said here on Monday night.

Sales of both two and four wheeled motor vehicles have been flat in the past five months, Ira cited.

The people's purchasing power is still weak and have no fund to spare for luxury, she said.
