2017 Mercedes-Benz S-class 550 convertible

First, the convertible top is a one-button control, up or down. The control button is in the center arm rest (which opens two ways, either toward the driver or the passenger—so clever!). The top can be opened or closed while you’re driving (at up to 28 miles per hour) so there’s no need to pull off the road when the mood hits you to put the top down.
