I have had my Passat for a full year now and I love it even more today than I did the day I drove it home. The car is so fun to drive, so comfortable and who can complain about 36 MPG back and forth to work and 43 MPG on the highway? I absolutely love this car and it is not bad to look at either. Pretty much the only things I would change is that I would add more cupholders throughout the vehicle and the ability to completely turn off the headlights without shutting down the engine (I have to go through a guard gate to get to work and the guards yell at me all the time because I have my lights on in their faces).
The seat heaters, fuel mileage, Monsoon stereo, heated mirrors, and looks of the car.
Add more cupholders throughout vehicle and stereo controls on the steering wheel.
