The upholstery; looks to still be in good shape, I would go ahead and repair it! You can repair it with a kit; that replaces the "hinges" will a seemingly, indestructible plastic versions! If you get another one; it will most likely, just ending up breaking again (fix it right; fix it for good)!
Thank you for sharing !!! I have been using my hair tie to keep that dam thing together for a year now. vw told me it would cost over 1000$ to replace the whole armrest
