Really happy with mine! No issues after a year and 12,000 miles. Plus the 24IR software update made a huge improvement in drivability. I'm 6' 1" and find the seat comfortable on 9 hour road trips, handling is decent, the little 1.5 is good on gas (recently got 34 MPG cruising at 80mph from Ft Lauderdale to Atlanta), lots of room in the trunk, good visibility while driving and I think it's a good looking car. Setting the cruise control to Comfort tames the car's eagerness to drop a gear and accelerate back up to speed.
I agree with quirkiness of the DSG. If you think of it like a manual, which I've driven my entire life and still own a manual car, the way it behaves makes sense and I think it drives just fine.
The only "improvements" I've made so far are Akebono ceramic brake pads at 2K miles, a layer of sound deadening (kinda like Dynamat) in the doors and trunk for a 1-2 db drop in road noise, better mid-bass and a satisfying thud when the doors close, and dynamic steering via Carista. All of it makes my ownership even better.
