So are German cars. Audi is a more expensive VW, Skoda and Seat are cheaper ones but the models are very much similar. The new Seat Leon looks like a VW golf now and so does the new Skoda Fabia. Mercedes is a more classy BMW. Opel was owned by GM before being bougt by Peugeot. Only Porsche, Audi and BMW make some unique sports cars.

I would rather buy a Japanese car any day. They're more reliable and you get more car features for the same amount of money.
