e320 cargo carrier
I need to buy a roof top cargo carrier for a 1999 E320 Wagon. The wagon has rails, but no crossbars. I'm looking at the carrier sold through MB, but I'm getting unclear information from several dealers and MBUSA. One dealer says I don't need the crossbars, one says I need the crossbars, and MBUSA says I probably need them, but they MAY not be necessary. I don't think any of them really know for sure.
So, are there any other E320 wagon owners out there with the factory carrier who can tell me if the carrier will mount to the roof without the crossbars?
Also, are there any owners out there who are using and can recommend another brand of carrier? I'm just looking to carry extra luggage and stuff (not skis or bikes).
Thanks!
