What is it like?

Reliability

So far, there haven’t been any recalls for this generation of CLS. <a href="https://www.whatcar.com/used-reviews/make/mercedes-benz">Mercedes</a>' reliability could be better, though, because&nbsp;the brand managed to finish only 24th out&nbsp;of 31 manufacturers in our&nbsp;2019 Reliability Survey.

Coupe

Mercedes’ line-up is vast – ranging from the A-Class family hatchback through to staple saloons such as the C-Class and E-Class, and onwards towards multiple SUVs, luxury saloons and even sports cars. Coupés and convertibles are thrown into the mix as well.

As one of the ‘big three’ German brands, Mercedes most often finds itself competing with Audi and BMW but more recently has found itself fending off Jaguar and Volvo, too.

Mercedes models are known for comfort. One example of this is the E-Class, because while the Audi A6 has a plusher interior and the BMW 5 Series handles better, the E-Class is probably the most comfortable for a long motorway journey.

MERCEDES-BENZ

Punchy diesel engines, lots of technology and tidy handling help mark the third-generation&nbsp;Mercedes CLS out from its competitors

Used Mercedes CLS 2018-present

The CLS is pretty evenly matched with its closest rivals in terms of daily fuel costs. The most economical according to the official WLTP figures is the 300d, with 45.6mpg. Both the six-cylinder 350d and 400d have a figure of 41.5mpg.

Petrol models are rather more powerful, but mild hybrid technology is fitted to all versions helps to boost efficiency. The four-cylinder 350 has a combined average of 36.2mpg, while the six-cylinder, four-wheel-drive 450 manages 34.0mpg. If you want the hotter AMG 53, this figure drops to 31.0mpg.

Road tax will be pricey, though, since every CLS costs more than £40,000 when new and will attract the highest rate of tax until the car is more than six years old. To find out more about the current<a href="https://www.whatcar.com/advice/buying/car-tax-changes-in-2019-%E2%80%93-what-do-i-need-to-know/n1153"> road tax costs, click here</a>.

Servicing costs at a franchised <a href="https://www.whatcar.com/used-reviews/make/mercedes-benz">Mercedes</a> dealership will hurt your wallet, because routine maintenance is considerably pricier than it is for other premium brands. At the time of writing, expect to pay £816 for two services, £1124 for three and £1632 for four. To put that into context, two services for an Audi under three&nbsp;years old will cost £468 for engines up to and including 2.0-litre models&nbsp;or £594 for anything above that.

The third-generation Mercedes-Benz CLS trails rivals such as the Audi A7 Sportback due to its firm ride, excessive suspension noise and cramped confines in the rear for taller passengers

Prices for a used Mercedes CLS at the time of writing start at £38,000 for a 350d AMG Line, but prices are changing relatively rapidly, because this is still a fairly new model.&nbsp;Use our free valuation tool to make sure you're getting the best CLS deal.&nbsp;

Check the value of a used Mercedes CLS with <a href="https://www.whatcar.com/valuations/">What Car? Valuations</a>

AMG Line is your only option here. This matters little, since there’s tonnes of equipment as standard, but you might want to look for a car with the Premium Plus pack,&nbsp;which includes the full smartphone integration the CLS usually misses out on.

The Driving Assistance Plus pack adds a lot of active safety technology, such as blindspot monitoring, which might be useful for those who do lots of motorway miles.&nbsp;

We’d recommend the 350d as the best engine choice. Unless you do only urban driving, the petrols aren’t a patch on the performance, economy and refinement of this diesel.

<h2>What we're looking for:</h2><ul><li>Plush ride and the ability to cruise in near-silence </li> <li>Powerful and efficient engine</li> <li>Space for passengers to stretch out in the rear seats</li> <li>Exquisite materials and build quality</li> <li>Endless luxuries on the options list</li> <li>Sensible fuel and tax bills</li></ul>

If you’re in the market for a luxury car, you’ll be after a sumptuous interior, a ride that can soak up the worst of the UK’s pockmarked roads and supreme refinement that allows you to travel at speed in near-silence.

Luxury

All models come with parking sensors and a rear-view&nbsp;camera to aid with parking, but still check for any external damage to the bumpers and bodywork. Also, make sure there aren’t any large chunks missing or nasty graze marks on the alloy wheels, since repairs can quickly become expensive.

There are some light interior colours available in the CLS that may show marks and dirt quite easily, so make sure there are no stains on the carpets and seats.

Long ago, when car ownership was a luxury for only the fortunate few, coachbuilders could take the chassis of an existing vehicle and build you a more striking body to sit atop it. Today, car makers are still reclothing existing platforms with more rakish designs, particularly after the success of the original&nbsp;<a href="https://www.whatcar.com/mercedes-benz/cls/coupe/used-review/n487">Mercedes CLS</a>, which was based on the&nbsp;<a href="https://www.whatcar.com/mercedes-benz/e-class/saloon/used-review/n491">E-Class</a>. So successful was the CLS, in fact, that it’s now in its third generation –&nbsp;and canny used car buyers can snap one up for a lot less than brand new one.

Powering the CLS is a range of three petrol and three diesel turbocharged engines. The 242bhp 2.0-litre four-cylinder (badged 300d) starts off the diesel range, followed by two versions of the same 3.0-litre six-cylinder unit with&nbsp;282bhp (350d) and 335bhp (400d). Petrol lovers can choose between a 295bhp 2.0-litre four-cylinder (350)&nbsp;and a 3.0-litre six-cylinder making 362bhp (450) or 429bhp (AMG 53). All four-cylinder engines drive the rear wheels, while the six-cylinder models have Mercedes' 4Matic four-wheel-drive system. A nine-speed automatic gearbox is standard across the range.

The driving experience is a bit of a mixed bag, because there’s very little wind noise and the engines are generally really quiet –&nbsp;particularly the six-cylinder diesels. Road noise is a bit more noticeable and there’s a surprising amount of suspension noise over bumps, and even models equipped with the optional air suspension struggle with pockmarked asphalt at lower speeds. Things do settle once you're&nbsp;up to a motorway cruise, though.

However, there is a certain amount of enjoyment to be had behind the wheel of a CLS, because the handling is rather sweet and there’s plenty of grip. The automatic gearbox swaps between ratios quickly, more so than that of the&nbsp;<a href="https://www.whatcar.com/audi/a7/hatchback/review/n151">Audi A7 Sportback</a>. Precise steering and progressive, smooth brakes complete what is a very pleasant package.&nbsp;

As you’d expect from a car with a lower roofline than a regular saloon, head room for anyone more than 6ft tall might&nbsp;become a problem whether you’re in the front or rear, particularly if the car is fitted with&nbsp;a sunroof. The CLS's driving position is alright, but the slightly offset pedals and bulge in the transmission tunnel by your left leg are a bit of a disappointment. The boot is still a decent size, although the small opening is rather awkward to get items through.

AMG Line is the only trim available on the CLS, so it’s very well equipped, with 19in alloy wheels, automatic emergency braking, lane-keeping assistance, LED adaptive headlights, leather seats that are heated in the front, keyless entry, a 12.3in infotainment system and a 40/20/40-split folding rear seat.

Cars fitted with the Premium Plus packed are worth looking out for, because that adds&nbsp;<a href="https://www.whatcar.com/advice/owning/what-is-apple-carplay/n1193">Apple CarPlay</a> and <a href="https://www.whatcar.com/advice/owning/what-is-android-auto/n1194">Android Auto</a> smartphone integration, an upgraded Burmester stereo, a 360deg camera and full electric adjustment for the front seats. The Comfort package adds nappa leather, air suspension and an interior fragrance dispenser, but it isn’t really worth paying extra for.
