Figure I'll get the negatives out of the way first.
1. The car is perched precariously on the edge of rough in terms of ride -- I have the base (Sport) model with the 17 inch alloys, and I'm kinda glad that I didn't go for the higher rims with 18s -- I'd imagine the larger wheel diameter would likely make the ride rather jarring, whereas currently with the 17s, it's only slightly on the rougher-than-average side.
2. There is quite a bit of turbo lag when starting from a stop with the DSG... I think sometimes it starts out in 2nd unless you are aggressive with the throttle, exacerbating the lag. Obviously worse when you have the A/C on.
3. As with a lot of cars I find with no tilting instrument cluster, I find that the "ideal" tilt wheel position will obscure the gauges. I am 6'1" if that matters.
4. The "leatherette" seating feels cheap and sticky during the summer... would have much rather had some type of cloth.
5. The DSG is too quick to shift out of 6th when the 2.0T still has plenty of give to ascend highway grades, so I generally put the transmission into manual mode to keep it in 6th when ascending grades. Never lose a tick of speed, so the kickdown algorithm is too aggressive in my opinion.
6. Radio controls are way too distracting to use while driving, especially simple things like tone adjustments or accessing different media. This isn't really a negative for this model -- just about every car in this class has this problem nowadays; some even more complex.
Now for the good points:
1. The 2.0T has a serious amount of low-end torque for highway cruising. Supposedly, the torque peak is somewhere around 1900 RPM, which is perfect for the 6th gear ratio, meaning, at reasonable highway speeds (65 and over), you will have little trouble ascending grades in the Northeast U.S. without constant shifts into 5th or 4th. I'd bet that the uplevel 3.6 does NOT do as well in this area as it does not have the low-end torque of the 2.0T, although it obviously has much more power elsewhere.
2. The DSG is generally smooth, though sometimes the 2-3 upshift can feel a little odd, but that may smooth out over time.
3. Steering feel is excellent for an electronic unit -- much, much better feeling than my parents '12 Ford Fusion Sport AWD, although not quite as direct as my previous Fit Sport.
4. Gas mileage is so far very good... easily over 30 on the highway, low 20s for the very short commute to work during the week (entirely non-highway).
5. Styling is very smooth and balanced.
6. Interior generally has a high-quality feel to it, other than the leatherette seats.
7. Very quiet whether on the highway or around town. You can barely hear the 2.0T most of the time (for better or worse).
That's all I can think of at the moment. I might update this after I've had the car a while.
