I purchased the Model S Whispbar Roof Rack System just over one year ago thinking I would need it for a road trip. Ended up not needing it and now definitely won't be needing it. The system was never installed. The box it shipped in was never opened. I'd love to sell it so I can get it out of my garage. It retails for $549 currently. It's brand new in box, so I'd like to get close to that and I'll cover the pricey shipping. More details on the Whispbar Roof Rack System here.
