This roof box was on my previous car, which I recently sold. I bought the box and roof bars directly through Mercedes-Benz of Bellingham. The car was always garaged, so the box stayed in great shape and is in excellent condition. All keys included. I held onto it because I thought I’d be buying another Mercedes, but I ended up buying a non-Mercedes vehicle, so I no longer need it.
Feel free to reach out if you have any questions. If the post is still up, the box is still available.
