The Volkswagen (Passat) CC, which is not coupe-cabriolet but comfort coupe, was one of the first 4 door coupes on the market. It was for some time also the only ‘cheap’ 4 door coupe you could buy, because the Mercedes CLS was a lot more expensive.
However it is time for Volkswagen to update the CC. The rumours are going, that the new CC will be a 5 door liftback, like the Audi A5 Sportback and BMW 4 series Gran Coupe. The Passat CC is longer, has a lower roof and has a lower bonnet. It will share a lot of parts with the normal Passat Sedan and Wagon.
