Used Mercedes GLC cars for sale or finance at 10.9% APR

Mercedes has sold the GLC since 2015, and gave it a noticeable facelift four years later. It’s Mercedes’ midsize SUV and is based on the C-Class. Most GLCs come in sporty AMG Line trim, which UK buyers seem to love, and there are a wide range of engine choices so it suits a wide range of people. If you’re someone with a ravenous appetite for licence-losing speed, there’s the full-fat Mercedes-AMG GLC 63 S.

All this also applies to the Mercedes GLC Coupe, which we’ve covered separately. The GLC has a pretty conventional SUV shape, while the Coupe gets a more rakish roofline for extra style points. The Coupe isn’t quite as practical as the GLC SUV, but there’s still plenty of room for a family and all the luggage that they’ll need.

The GLC range was replaced by a new model in 2022, following on from the refreshed C-Class. This gets even more tech and even more space, and a larger battery for the plug-in hybrids, so it’s worth looking out for if you can afford it.

You’ll take up a little over 4.6 metres of space in the outgoing GLC, and fractionally more in the very latest car. And fractionally more again in the GLC Coupe. Luckily, all come with a reversing camera and parking sensors, so you can avoid backing it into the garage door every time you park on the driveway.

The GLC offers plenty of space for four adults, but five up can feel a little tight because of the tall transmission tunnel. There’s plenty of adjustment for the driver. Wide-opening rear doors and the raised ride height compared to a C-Class means it’s easy to get young children in and out. The rear seats fold individually so you can carry passengers and large items.

At 550 litres, the boot is the same size as what’s on offer in the X3 and Q5 – although it’s worth noting that hybrids get 395 litres, or barely more than a petrol-powered A-Class. The 2022-on GLC has either 600 or 400 litres, depending on the powertrain.

GLC buyers are spoiled for choice, with everything from frugal four-cylinder diesels and plug-in hybrids right through to thunderous V8-powered AMG models. Just don’t go expecting a choice when it comes to the gearbox, as all GLCs have automatic gearboxes and all are four-wheel drive.

In the 2022-on GLC, the engines have the same badging as the ones below, but the petrol and diesel engines benefit from mild-hybrid technology to improve fuel economy.

Yes, all GLCs come with Mercedes' 4Matic four-wheel-drive system, whether you pick a petrol, diesel or hybrid engine. It gives a little extra grip in wintry or slippery conditions but the GLC doesn't have quite the same off-road ability as a dedicated 4x4 like a Land Rover Defender – not that you'd probably want to risk taking your GLC off the asphalt.

The Mercedes GLC will cost a little more to maintain than a similarly sized SUV from a less premium brand – you're paying a bit more for the sheer amount of technology on board. Mercedes does offer service plans that split routine servicing into monthly chunks that might help you budget easier.

Often, premium brands like Mercedes don't do well in reliability surveys because there's so much technology that could potentially go wrong. But Mercedes performed strongly in 2021's Driver Power owner survey, with the GLC performing no worse for reliability than the majority of other cars in the survey.

There are only two sets of Isofix points in a Mercedes GLC, although you could conceivably fit a non-Isofix car seat on the front passenger seat. Check out our list of the best cars that can fit three car seats here.

Petrol and diesel GLCs have a large 550-litre boot (measured to the parcel shelf) – that's about 50 litres more than you get in the C-Class Estate, and should be more than enough for family life. Fold the individual rear seats down and you get a 1,600-litre space, provided you're happy to load to the roof. The extra hardware needed for the plug-in hybrid engines means the GLC 300e and GLC 300de offer 395 litres of space.
