FYI - we got our Passat's hitch (for a bike rack) at U-Haul fairly inexpensively. They did a terrible job - the rack is clearly tilted about 3 degrees clockwise. We're able to balance the bikes to counter the awkward tilt, but I have longterm wear concerns. I'm sure all U-Hauls are different, but just thought I'd pass on the advice to check out wherever you are considering with others first.
I will say that a hitch mounted bike rack is convenient compared to other types. We're happy with it overall.
