I believe it only comes on the 550 in the U.S and 350,450 and 550 with sport package in Canada and UK. You have the 19's which do not come with the sport brakes.

Ok I wasn't aware that the appearance package determines the cross drilled brakes. Our 2013 with appearance package does have the cross drilled.

I spoke with the dealer today and my salesman confirmed they have removed the cross drilled rotors from the GL350 and GL450, the GL550 and GL63 still has them.

I highly doubt that.

maybe they were changed because of premature warping issues being reported by many 2013 model owners?
Here is a link to an article comparing different types of rotors

Maybe Fab can give us some insight.

The article is misleading, most sport cars, super cars, hyper cars have drilled brakes. i.e C, E, S, Class, 99% of Porsche's etc etc.

I was actually on the lot with my salesman and we walked the sales lot together and all of their 2014 GLs that were not the GL550 and GL63 came with non-drilled brakes. Our 2013 GL450 had the drilled brakes.
