As far as criticizing Hyundai, try and understand the car industry first.
Hyundai jumped in the game very very young. And as Justin said - they've come a long way... what he didn't add was "quickly." The company is trying to keep up in a market with companies that've been in the game for at least twice as long as they have. Many other car companies can't keep up with the US as far as all the safety standards and integrity. Though successful, Kia is not at the level of Hyundai. Nonetheless, Hyundai - They are successfully marketing cars in the US and now have released the Genesis.
My speculation is the genesis is going to be a unique car in the tuning world... not only the coupe but also the sedan. Similar to how sedans are a "style" in japan whether its tuning or drifting (cefiro is one example). I'm waiting for a twin turbo v8 monster. lol
There are hundreds of car companies in China (some of which made an appearance at this years auto show) that aren't making it here but Hyundai manages...
Not to mention... yeah stealing car ideas... How about the Pontiac G6, Scion TC, 8th gen Honda Accord coupe, and a few others all having the same rear... Oh and my BIGGEST complaint is Jaguar hiring the same designer as Aston Martin....
