    I purchased this harness bar about four months ago and absolutely love it. The fit and finish are incredible, and I love the way the side bars tuck up and out of the way. The pictures here on their website do not do the harness bar any justice. I highly recommend this harness bar, and in my opinion there is not a nicer or more practical harness bar on the market. The cross bar can be easily removed so passengers can sit in the back, but I would recommend putting a small piece of foam or other protective material over the ends to cover any sharp areas exposed while the center section is removed.

    Bought this bar and installed in a couple hours. The connectors were a nice tight fit and can be removed with minimal hassle. A rubber boot on the end of the connector attached to the uprights on both side make the back seat as usable as it can be on a S550. Great fit and finish.
