2012 Year Specific Mercedes Benz S550 Sunroof Glass. The sunroof is in good used condition. Measurements are 34 3/4" long and 20 3/4" wide. **We have included the measurements so you can match up your existing roof with ours, as aftermarket sunroofs have become very popular, if you have a switch that looks like any in the last picture, you have an aftermarket, contact us we can help. Also be wary of sellers stating this sunroof will fit other years, it will not, this sunroof was specific to the 2012 S550. This glass panel was removed from a Mercedes Benz that had a blown engine so there is no unseen damage on this panel as is found with a majority of sunroof glass panels that are removed from wrecked vehicles. Often times on a wrecked vehicle, the metal trim around the glass, under the seal, will incur slight bends which will make the panel leak soon after. We have been dealing in sunroof glass panels for 20 years now and only sell the panels that come through our shop that are off of vehicles that have not been in major accidents. We also 100% inspect and clean the panels, especially the seals, in an effort to identify any imperfections that may cause issues down the road. The glass panels are inspected after removal from the vehicle as the seals can be easily damaged during the removal process. The sunroof comes read to bolt in. Please contact us with any questions that you may have.
