There are more than 5 companies in Japan guys, lol. It's true though, the zaibatsu make a ton of stuff, just sprawling companies taking up your money to eat, breathe, sleep.
That Daewoo is from the older Daewoos that were designed by Italdesign (?I think) - they were actually some of the better looking cars in Korea, because Hyundais a generation or two ago were fugly. They still litter the streets here because there are no age/condition restrictions on cars like Japan. Korean streets are an eyesore with all the heinously designed cars. The new Hyundais look a bit better than the old ones, but I still find them kinda obscene looking with lots of convoluted lines and try-hard styling - Korean cars all have fake Audi LED lightstrips or glowing halo rings, chrome-lined headlights with tons of veins and shit, huge character lines in the back - it's like all the nice cars in the world got together and had ugly kids.
Funny thing about the badge engineering thing you guys were talking about - the Koreans took it one step further and used to buy old tooling for superseded foreign cars, and brought it all to Korea to remake these cars, as R+D was too expensive for the Koreans, and also because they could turn out a better package that way and make and sell domestically without having to sell with an import tax. Some examples:
-Daewoo Arcadia. Daewoo bought all the tooling from Honda once Legend production was over in the mid 90's, and made a US-spec Acura Legend and slapped Daewoo badges on it.
-KIA Elan - KIA bought the tooling for the Lotus Elan in the mid-90's, dumped the Mazda 4cyl, and put in their own crappy 4cyl. Cool car though, genuine import sports car looks in a country where this kind of car was only a dream at the time. Was insanely cool when it was sold here.
-Ssangyong Chairman - a stretched version of a W124 260E (? maybe a 300E) - tooling bought from MB in the 90's - they rebodied in their own body, but it looks like a Mercedes anyway, that was the point - it was supposed to be kind of a domestically made W140 Benz competitor. Good idea, but they still make this car after years and years, and it's still the same 1984 E-class under the skin. =\ Ssangyong also bought from Mercedes some diesel engine tooling that they put into a body on frame SUV.
-Hyundais have all been old Mitsubishi technology for years, many still are, but that's changing a little I guess. In fact, the Genesis 2.0T coupe has a modified version of that Mitsubishi 4G63 engine they've made forever. This is also the reason why Hyundais used to be horrible - they were old Mitsubishis which themselves were terrible cars.
Basically, I think up until recently, no Korean cars were entirely domestically made from scratch, they were based on old outdated cars from overseas. Many were crappy. Some were actually good though, the Daewoo'd Honda Legend and the KIA Elan were good products, IMO. The Ssangyong E-class was kinda cool at the time considering it was only like $30K and a real Mercedes was like, $100K - but they restyled that car twice to look less like a Mercedes in each restyle. =\
