    Since no picture was available, I trusted the description. It was not a headliner, due to a misprint it was a storage system. The quality of the product shipped was excellent, great appearance and a great value. Package was in new condition and shipped with care. Please note that the seller rectified the misprint. I would definitely do business with them again.

    The seller actually sent me MAHLE valve cover gasket set instead of victor reinz but they are mostly the same anyways. I contacted the seller about it and they were excellent at quickly responding and offering to exchange product. The seller was great at communicating and making sure I was happy and I definitely would purchase from them again.
