Basically, in Korea you have to have a distribution network and provide after-service. The Korean is a sophisticated consumer, not unlike the Japanese in terms of their requirements, so it's not surprising that the car that is selling the best in Korea is the BMW right now.
That's what my reference was. The cars don't have to have the driving wheel on the other side of the car or anything like that, but there is a high level of care and feeding for the Korean consumer.
