With the TDI, I'm easily getting 45+ on the highway. The in-car MPG is a few MPG over actuals. Drove 600 miles in my first tank of gas. Even with a bike rack with three bikes on the back of my car (lots of extra drag), I was getting 40 MPG on a 180-mile highway trip. Fuel economy is better than excellent for a non-hybrid.
Premium Fender audio system with touch-screen and satellite radio, plus all the Bluetooth features to hook into your phone, are excellent. Granted, I'm coming from a car that had none of these, but the VW stuff is easy to use and very intuitive. I would have liked a few more steering-wheel controls, but the big buttons on the radio itself makes you not miss having more.
I read some other reviews about the "cheap" interior and "hard plastic" but there is nothing to complain about here considering the price point of the car. Sure, a few buttons are not exactly high-end (the climate control dials and remote mirror controls come to mind), but overall it's a solid, well laid out interior with comfrotable seats that can adjust to different driver sizes for comfort (I'm 5'10, my girlfriend is 5'1, and both of us enjoy driving the car).
Trunk is enormous given the size of the car, and there is plenty of interior space. I am amazed how much I packed in this car for a week-long trip with my kids.
