As a VW employee I would just like to make a few points clear.
The aim of the passat CC is not to make money directly, VW know it will lose money. The aim is to keep Passat drivers in Passat, and not migrate elsewhere. By introducing the Passat CC it raises the profile of the standard Passat, encouraging existing and new Passat drivers to buy again. People aspire to a particular car. The Passat CC encourages existing Passat drivers to aspire to the Passat, as opposed to the A4 or BMW 3 Series.
2nd, for a person who appreciates a car for what it is, as opposed to its badge, I can honestly say the Passat CC is the first car VW have produced in years that I have actually desired. It is much better looking in the flesh. Well finished, nicely equiped, and I would have one over an A4, C or E Class, or BMW 3 Series any day. Its much nicer to drive.
It may not hold its value, or appeal to all VW tastes, but it is a fantastic car. A VW at heart.
