How much is Perdana maintenance cost?

Malaysia is a country full of surprises. Now, the hottest topic in the country is about Proton Perdana maintenance fee. The story started when Terrenganu government wants to buy Mercedes as official car. They argued the car is of poor quality and 4 years maintenance fee is about 117 million ringgit.

The figure is stunning. Anyone with a logical mind would immediately think it is enough to buy how many new cars already? Can the car maintenance fee go to this extent? I think most probably everyone would have a common answer. We hope the truth would be revealed eventually. How could maintenance fee cost so much?

Another interesting issue that it brought up is whether Proton car quality. Is it so poor in quality?
