My GTI had DSG. It wasn't my first choice, but I went ahead and compromised on that in case my wife ever had to drive the car. Annnd she never even once sat in the driver's seat. After that car was gone I decided I was sticking to, well, stick.
Anyway, driving impressions. Normal is pretty much like an automatic. Sport lets it rev a bit higher. Manual mode did have very quick shifts but there were a handful of times that I said "GODDAMMIT SHIFT NOW" and it took a bit longer than I wanted. What turned me off a bit was the maintenance schedule on DSG. Every 40k miles was a $450 fluid and filter change. From what I've heard the costs may have decreased since the six years or so ago that I had the car.
Also the Abarth will be available in an automatic soon too. Uh, no bias at all. Nope, none.
