The 220 d and 250 d emit just 129g/km of CO2, which is less than any Audi Q5 or BMW X3 and makes the GLC cheaper than those rivals to run as a company car. The 350 d emits more at 159g/km, so doesn’t make the best company car choice, nor the best private one if fuel economy is a primary concern.
Overall the GLC makes reasonable sense if you're a private buyer, although it's predicted to depreciation faster than the Q5 and Land Rover Discovery Sport. Likewise, those rivals will cost you less each month in finance repayments.
As if often the case with Mercedes models, servicing costs are higher than the class average and discounts smaller than you can expect on some rivals. However, Merc’s finance deals are often competitive, so if you’re looking to buy on a PCP, be sure to compare it to its rivals.
Mercedes-Benz GLC equipment
Although entry-level SE trim gets you plenty of luxuries, including climate control, a powered tailgate, electric front seats, keyless start, a DAB radio, a reversing camera and cruise control, you do miss out on all-important sat-nav.
That comes as standard on Sport trim and above, where you’ll also get rear parking sensors, bigger alloys, heated front seats and LED headlights. However, given the relatively small price jump from Sport to AMG Line, it’s the range-topping trim that we’d recommend most. This is mainly because it brings firmer but, surprisingly, more comfortable suspension, but you also get styling upgrades that many buyers will value.
There’s really no need to plunder the options list, although metallic paint is worth considering and you might want to upgrade to real leather seats (faux leather comes as standard).
Mercedes-Benz GLC reliability
This GLC doesn’t have a predecessor to gauge reliability from, but Mercedes as a brand finished a disappointing 32 out of 37 manufacturers in our most recent reliability survey. At least the 2.1-litre diesel engine all models are fitted with is well tried and tested – it’s been around for years.
The GLC comes with a three-year/unlimited-mileage warranty and three years of breakdown cover, which is similar to what most rivals get.
Mercedes-Benz GLC safety & security
All GLCs come with a collision prevention system that can automatically apply the brakes to help prevent you running into the back of the vehicle in front. There’s also a tyre pressure-monitoring system to alert you early if you have a slow puncture. All editions get seven airbags and a system that can detect if you’re getting drowsy on a long journey, too.
This all helped the GLC score impressive marks in its Euro NCAP crash test. It was awarded the maximum five-star overall rating, along with scores of 95% for adult protection, 89% for child protection and 82% for pedestrian protection. All of these scores were higher than the rival Land Rover Discovery Sport managed.
An alarm and engine immobiliser are standard on all versions, while security experts Thatcham awarded the GLC five out of five stars for resisting being stolen, and four out of five for resisting being broken into.

This entry-level trim gets you plenty of luxuries, including 17in alloys, faux leather seats, climate control, privacy glass, a powered tailgate, electric front seats, keyless start, a reversing camera and cruise control. You do miss out on all-important sat-nav, though.
Comes with everything that’s standard on the entry-level SE, plus rear parking sensors, larger alloys, heated front seats and LED headlights. You also get sat-nav, so it’s worth the price premium. However, we think range-topping AMG Line trim makes even more sense.
Our pick AMG Line
AMG Line might be the most expensive trim in the GLC range, but it’s actually our favourite. That’s largely because you get a firmer, but more settled, suspension set-up and sharper handling for a relatively small price premium over mid-spec Sport trim. Other upgrades are mostly cosmetic, but many buyers will value them.
