Surely after the recent failure of the Golf Plus MPV, and the unpopularity of the last estate and saloon models of the Polo (back in 1996), VW would have realised by now that creating all these niche products is a silly idea? All that happens is they don't sell and end up having worse residuals than the models they are based on. By buying one you loose more than you gain.
VW should stick to the bread and butter models.
