The GLC 220d has 19-inch wheels, Artico vinyl upholstery, and the features common to all GLCs – which means it comes pretty well stocked.
Spend more on a GLC 250 or 250d and you get the more powerful engines outlined above, and some more cosmetic, comfort, and driver-assistance items.
The added driver-aids are arguably the chief sweetener. They include Distronic Plus, which combines a sophisticated adaptive cruise control with an enhanced auto-braking system. As well as adapting your cruising speed to other traffic on the highway, it can hold your place in crawling traffic.
Active lane-keeping assist and active blind-spot assist add corrective action to the passive blind-spot alert on the GLC 220d.
The GLC 250 and 250d also feature leather upholstery, 20-inch wheels, and dark-tinted privacy glass for the rear windows. Keyless-Go allows fingertip locking, unlocking and starting, provided the key is in your pocket or bag.
Mercedes-Benz also offers extra-cost options in packages.
A Seat Comfort Package adds heated front seats, additional power adjustment for seat cushions, headrests and steering wheel, and a memory for seat and mirror adjustments (so that you can restore your settings quickly after a companion has driven the car).
The Vision Package brings you a long glass sunroof with two roller sunblinds, plus a head-up display that projects the speedo and other instruments onto the windscreen, just below your line of sight.
The COMAND Package combines an impressive 13-speaker Burmester sound system with a bigger, 8.4-inch, colour TFT screen, high-def navigation, a single-disc CD/DVD player, a 10GB on-board hard drive, and multimedia enhancements.
Then there is AMG Line, which completely alters the character of a GLC. It gets you 20-inch multi-spoke alloy wheels, firmer suspension, rear privacy glass, a flat-bottom steering wheel with gearshift paddles, and several external and internal styling tweaks.
An important option for anyone who wants to use their GLC outside cities and freeways is Air Body Control suspension, which brings you a much more resilient and disciplined ride (using multi-stage air springs and electronically controlled damping).
The Off-Road Engineering Package includes the air suspension but takes it a step further. Among its additional off-road driving modes is Rocking Assist, which raises the body 50mm and adjusts the traction control to help you free a stuck car. There is also under-engine protection. And if you order it for a GLC 250 or 250d, it substitutes 19-inch alloy wheels and tyres (which are better on unsealed surfaces) for the standard 20s.
