Available in standard roofline and sleeker "four-door coupe” versions (the latter is shown above), the compact Mercedes-Benz GLC is elegantly styled inside and out. A “superior” rated auto-braking system comes standard, though a forward collision-warning system remains optional. A blind-spot warning system is a standalone option, while lane-departure warning and lane-keeping-assist systems are available as part of the (costly) Premium Driver Assistance Package.
