I've got exactly the same dilemma, current car is a Passat 150tdi Sport Estate due for renewal and is no longer available on my employers list (cut backs), as such I've narrowed my choice on a somewhat limited list to either a Superb 1.6tdi Greenline III SE Tech or the Superb 1.6tdi SE Tech DSG. I've got a Greenline currently on trial and the gearing seems high for a 1.6, as such there is a lot of gear changing around the 25 to 40mph region whereas my Passat has the flexibility to remain in fourth throughout. Question is should I spend the extra £36.70 per month on tax for the DSG, is it worth it ?
Other dilemma is colour choice but that's another story (Candy or Moon White).
