Well for all you know, the Phaeton could one day in the future be a vintage automobile - for the most luxurious VW ever built that nobody wanted. Till then, the Phaeton faces a dark, danky future. Maybe once they introduce the 4-door coupe that's situated between the Passat's and the Phaeton's price, it would iron out some issues of brand recognition.

It would take time and effort on VW's part, without doubt.
