Used Mercedes SLK review

Although a Mercedes SLK wasn’t a initial coupe-cabriolet (Peugeot got there first, 6 decades earlier), it was a initial with tellurian reward appeal. The strange SLK (codenamed R170) arrived in 1996, afterwards in 2004 an all-new second-generation indication went on sale, codenamed a R171.

While a Mk1 was a really good car, a second book was a large improvement, with a most improved pushing experience, stronger levels of build peculiarity and a most smarter pattern inside and out.

Add in some glorious engines that operation from amiable to wild, along with some really sharp gearboxes, and it’s easy to see since a SLK is so popular, even if it’s some-more of a cruiser than a pin-sharp pushing machine.

Used Mercedes SLK - full front


When a second-generation SLK was launched in Jul 2003 there was a choice of 163bhp 1.8 or 272bhp 3.5-litre V6 petrol engines (SLK 200K or SLK 350), as good as a high-performance variant, a SLK 55 AMG, with a supercharged 360bhp 5.5-litre V8.

Which one should we buy?

There is no diesel SLK Mk2, so it’s a choice of four, 6 or eight-cylinder petrol engines. The SLK 350 is super-smooth, yet a four-cylinder SLK 200K is also quick, polished and well-spoken enough. It also costs reduction to run than a SLK 350. However, it’s value shopping a facelifted automobile (from Apr 2008), since a additional 21bhp creates some-more of a disproportion than we competence think.

Used Mercedes SLK - rear

Most SLKs have a discretionary automobile gearbox, that suits a car’s inlet really well; a categorical reason not to buy a primer is that it competence be tough to sell on later. Mercedes offering a lot of options, including sports cessation that significantly firms things adult – yet we competence find it uncomfortable.

Alternatives to a Mercedes SLK Mk2

The Audi TT is some-more serviceable in a winter since it has possibly front or four-wheel drive, yet a cabrio is a soft-top, so we have to collect possibly a Roadster or a coupe.

Like a TT, a BMW Z4 is good built and a initial era came in cabrio or coupe forms; a Mk2 (from 2009) was a coupe-cabriolet. With rear-wheel drive, it’s some-more of a driver’s automobile than a Audi, and it sounds nicer, too, generally in six-cylinder form.

The Porsche Boxster is a best of a lot to drive, though, and is beautifully built, as good as being surprisingly practical, while a Honda S2000 provides copiousness of thrills and glorious trustworthiness for not most cash.

What to demeanour for: 


The SLK’s electrical complement is reliable, yet if a wipers don’t  work, check a carp is sealed properly; there’s a reserve switch that cuts in and disables them. 


Folding hard-top is arguable if lifted and lowered regularly. If it’s left in one position for too long, though, a motors seize up, so check it all works. Repairs can be costly. 


SLK doesn’t generally interest to fan drivers, yet some owners get carried divided with character over piece and fit 19-inch wheels, that destroy a car’s ride.


The SLK isn’t a large car, yet it can still be wily to park since it’s tough to see where a corners are, generally when reversing. It’s value shopping a indication with parking sensors.

The SLK’s cabin peculiarity is good, yet facelifted cars are noticeably improved than their predecessors. An choice value carrying is a Airscarf, that blows comfortable atmosphere on to your neck; it’s shining for top-down winter driving. Practicality is flattering decent; a foot has 300 litres, or 208 litres with a roof down. 

Running costs

Facelifted SLKs need upkeep annually or any 15,500 miles; progressing cars have non-static servicing that allows adult to dual years between garage visits. Services swap between teenager and major, labelled during £235-£272 and £400-£450 respectively, depending on engine fitted.

Motors are chain-driven, so cambelts aren’t needed. Fit uninformed hint plugs any 48,000 miles or 4 years, during £100-£200 depending on a indication (some engines are twin-spark). The long-life coolant needs to be checked during any use and transposed or surfaced adult as necessary. Brake liquid should be transposed any dual years (at £90), while an annual air-con check is needed; a regas is £100.

The second-generation SLK has been removed usually once, and now that a automobile has been out of prolongation for 5 years, hopefully it won’t be again. That debate came in Nov 2008 and influenced 72 cars, also including a M-Class, CLK, E-Class, C-Class, A-Class and R-Class.

The problem associated to SLKs built adult to Oct 2008, that could humour from a fuel supply not shutting off in an impact. A control section was during fault; a repair replaces a unit, that was commissioned with updated software.
