Maximum Speed For Roof Operation
I'm considering buying a 2017 SL550. I have found multiple articles stating the roof can be raised or lowered at speeds up to 25 MPH. The seller tells me maximum speed is 3 MPH. When I drive this particular car it is indeed 3 MPH. My test drive was perfect, with the possible exception of the roof operation. So what does the forum think???? 25 MPH or 3 MPH in a 2017 SL550?

I believe it is supposed to be up to 25 mph if the system is activated below 3 mph. In other words if you are at a Red light, activate the roof, and then the light turns green you can keep activating the roof as you move forward. This way you do not **** off any drivers behind you at the light. Having said that my ‘17 will not do as advertised. I have to be stopped with my foot on the brake or in park for it to open or close. There must be a internal setting to change this but I never have the need to open or close while moving so it is a mute point for me.
PS-The SL is my favorite car to drive. Don’t let this one minor glitch keep you from getting one!

I wonder if the R231 roof mechanism is still made by the same company as the R230. Used to be CTS, a company jointly founded by Mercedes and Porsche.
They made the folding roofs for about every convertible , including the Corvette
Now it’s owned by Magna...
