Yea, regardless of size, the lines and appearance are much better.
I've got two kids so the size is fine for me. On a long trip we can fill my outback and roof box with stuff no prob.
The AC is broken in my GTI (and in the SUV). With the high temps and humidity, I got 34 mpg driving from KMart to Logan Airport yesterday. I didn't realize how costly it is to run the air conditioner in that car.
Snow tires and the yakima box give my car a bigger mileage hit than the AC. My mpg average is always 2-3 miles higher in the summer.
