Sportrack SR7016 Cargo Box
Just finished an 800 mile trip in our GC with a Sportrack SR7016 up on the roof. I kept the speed below 75mph (most of the time), wind noise was noticeable but not what I would call excessive. Probably lost 3mpg average with the cargo box up top. The 16 cubic foot size of the SR7016 was perfect for our WK2; the front of the box was about even with the front of the sunroof and in back still had plenty of room for the hatch to open fully. Overall I'm pretty happy with how this box worked out, especially considering I got it from walmart, shipped to my local store, for around $250.
