How come most JDM engines have low mileage although some are 8-9 years old?
The reason is that Japan has one of the most rigorous and expensive car inspection systems in the world, the cost of which often ranges from $1,000 et $2,000. Although new cars are exempt from the requirement, once an automobile reaches its third birthday, it must undergo this inspection every two years. After an auto is a decade old, the inspection must be done annually. At this point, most Japanese write off their cars because of the cost of the inspections and buy new ones. This practice has been used to boost car sales in Japan and give carmakers such as Honda, Nissan, Mitsubishi, Subaru and Toyota, advantages to compete in the international market.
