Let me clear things up...
He was NOT the head of Hyundai Motors. He was in charge of Hyundai Asan, which has been under media scruitny as of late due to the forementioned blackmail scandal. Hyundai Motors should see no effect from this incident.
Just FYI, one of the reasons why this guy's father (deceased a few years ago) ran for presidency a while back was because he was sick of being 'forced' to do government chores and giving bribes. This man probably could have avoided this tragic end had his brother been succesful in his bid for presidency last year. But no, he dropped out of the running, and with new regime comes new headaches for chaebols vulnerable to all sorts of blackmails due to their business practices (that are necessary to operate in the economic/political environment, by the way).
Also, Hyundai Motors is doing really well. Hyundai group is struggling due massive amount of defaults from its customers belonging to its credit card unit, but that should pose no long-term problem for Hyundai Motors.
As for Hyundai cars, one of them was my first choice on my last shopping trip! Tiburon/Tuscani/Coupe is a very fine looking car. That car was ahead of Acura and VW
when I went shopping. I ended up with a Honda in the end due to insurance reasons, but I would not hesitate buying a Hyundai car in the future. The 10 year warranty should not be around much longer once the economy picks up. This was made clear by the very person heading the US-unit of the Hyundai Motor goup. It has already achieved its goal - bringing customers in. The products are obviously withstanding the test of time.
