- Distinctive glass roof panel
Cons
- Less engaging to drive than rival convertibles
- Antiquated technology interface
- Snug interior, even by convertible standards
What's new
- New SLC 300 and AMG SLC 43 Final Edition packages
- Part of third Mercedes SLK generation introduced for 2011 (renamed SLC Roadster for 2017)
Overview
It's fair to say that the 2020 Mercedes-Benz SLC, at least in automotive terms, is now receiving AARP enrollment letters in the mail. The current-generation car debuted all the way back for the 2011 model year. While there have been some updates over the years, it's still the same basic car underneath.
Cost to DriveCost to drive estimates for the 2020 Mercedes-Benz SLC-Class SLC 300 2dr Convertible (2.0L 4cyl Turbo 9A) and comparison vehicles are based on 15,000 miles per year (with a mix of 55% city and 45% highway driving) and energy estimates of $3.93 per gallon for premium unleaded in Virginia.

Avg. Compact Car
Rival luxury roadsters such as the BMW Z4 and the Porsche 718 Boxster have undergone full redesigns since then. Even compared to other Mercedes-Benz cars, the SLC feels as if it was plucked from a different era.
It isn't all bad news. The SLC's styling is handsome, and its retractable hardtop design makes it quieter at freeway speeds than its soft-top rivals. It's also available with a long list of luxury features. If you really want a hardtop, check out the SLC. Otherwise we suggest looking elsewhere.

Edmunds Rating
Our VerdictThe Edmunds Vehicle Testing Team evaluates a fresh batch of vehicles every week, pairing objective assessments at our test track with real-world driving on city streets, freeways and winding roads. The data we gather results in our Expert Ratings. They’re based on 30-plus scores that cover every aspect of the automotive experience.
We tested the Mercedes-Benz AMG SLC 43. It's quick and at times engaging, but all SLC models are showing their age. This generation of Mercedes' drop-top is nearly a decade old and competitors have eclipsed it in almost every way. Even compared to other Mercedes-Benz vehicles, the SLC looks and feels dated, especially inside. The retractable hardtop is a plus for highway driving, but it's not enough to put it ahead. The game has moved on, and the SLC hasn't.
Rated for you by America's best test team.
Performance
7.5/10
How does the SLC-Class drive? The AMG SLC 43 encourages spirited driving thanks to its strong turbocharged V6 engine. But the final result isn't as engaging or thrilling as an Audi TT, Jaguar F-Type or Porsche Boxster. Some of these alternatives may be slower, but the greater sensation of speed and confidence is in their favor. While the SLC 43 handles well enough on smooth pavement, it can feel a bit unsettled on broken surfaces as the tires struggle to maintain their grip.
The gear changes are smooth and quick in everyday driving. The auto engine stop-start system causes shudders in the cabin and is a little slow to react. It occasionally turns off the engine just before you come to a full stop, resulting in an inelegant lurch.

Comfort
7.0/10
How comfortable is the SLC-Class? Its folding hardtop roof is quieter than competitors, and the powerful climate control — complete with a breeze for your neck — is welcome. The seats are supportive and offer enough bostering to keep you planted while cornering yet don't feel confining.
The AMG SLC 43's ride quality is about average for the class. You feel every flaw in the road and there's substantial jostling over undulations, though it doesn't feel needlessly harsh. Overall, the SLC doesn't stand out from, or trail, the segment when it comes to comfort.

Interior
6.5/10
How’s the interior? The interior is showing its age. Since the SLC debuted, the entire Mercedes lineup has adopted a more graceful and upscale cabin design. The technology has become more prevalent and easier to use too. The SLC's controls aren't as intuitive as those used in newer models, and some are hard to read in daylight.
It's snug inside the SLC too, though we wouldn't call it cramped. The low roof makes it feel smaller than it is and hurts both forward and rear visibility. The top itself folds in about 20 seconds.

Technology
6.0/10
How’s the tech? If there's one thing that ages quickly, it's technology. Mercedes has updated its infotainment system multiple times since the SLC went on sale. The old-generation numeric keypad and needlessly redundant buttons bring up nostalgia, but not in a good way. At least everything works as it should, and Apple CarPlay and Android Auto smartphone integration is available.
The SLC comes with a decent level of driver safety aids. But, like the other in-car tech, they are much less refined than Mercedes' more recent products. The traffic-adaptive cruise control, for example, keeps a good gap but frequently taps the brakes instead of downshifting on a hill, causing small lurches. Other systems are difficult to operate.

Storage
5.5/10
How’s the storage? What did you expect? It's a roadster, and the folding hardtop further cuts into cargo space. The trunk isn't generous, but that's expected of a folding-hardtop convertible. There's enough luggage space for a couple's weekend getaway with the top up. With the top down, only a single carry-on suitcase will fit, so pack light.
The interior isn't any better. You'll find few places to put items such as your smartphone or sunglasses, even fewer than in other roadsters in this class. These aren't the most practical vehicles around, but even by the class standard, the SLC falls short.

Fuel Economy
5.0/10
How’s the fuel economy? The EPA estimates fuel economy at 23 mpg in combined city/highway driving for the SLC 43. The SLC 300 is more economical at 27 mpg combined. Both numbers are below average for this class of car. Our SLC 43 test car posted a lackluster 21 mpg on our 115-mile mixed-driving evaluation route.
Value
5.0/10
Is the SLC-Class a good value? It's hard to justify the cost of this Mercedes considering the newer convertibles from Audi, BMW, Jaguar and Porsche. The alternatives give you more for the money, especially given the age of the tech and overall design of the SLC.
Wildcard
6.0/10
For the few who are considering a roadster, emotion plays a big role in this decision. While it can be fun, the SLC 43 AMG doesn't quite make the heart sing with rapture as some others do. The exterior styling has held up well, but the interior looks and feels every bit of its age. Take one look at the competition and you'll see just how far things have come since the SLC debuted.
Which SLC-Class does Edmunds recommend?
While the SLC 300 offers a decent open-air experience, we suggest stepping up to the more powerful and much more engaging AMG 43 model. In addition to the twin-turbo V6, it comes with more standard equipment than the base model.

Not a hairdresser's car.
Will, 03/12/2019
2018 Mercedes-Benz SLC-Class AMG SLC 43 2dr Convertible (3.0L 6cyl Turbo 9A)
*The interior is far from cheap. Almost everything is leather, suede, soft to the touch and high quality carbon fiber. The ac temperature wheels are kinda cheap plastic but that's about the only thing that's not grade a quality, and they're really satisfying to turn.
*It has dynamic control. 4 modes, eco, comfort, sport and sport plus. In comfort it's really quiet, feels like a regular … luxury car. Sport makes it a bit louder and stiffer and somewhat more fun. Sport plus makes it really aggressive, like constantly in the boost range, crazy throttle blips while downshifting and obnoxiously loud. Super stiff and handles like it's on rails in sport plus. I'm a die hard manual guy and I fell in LOVE with sport plus.
*It's quicker than you think it is. When you get on it, it will break loose at high rpms even on dry pavement. I love that it puts you back in the seat when boost hits.
Only complaints I have are that the steering is really numb compared to how well it handles and it can be tail happy in corners.

Fabulous Fun!
Maggie B., 06/18/2020
2020 Mercedes-Benz SLC-Class SLC 300 2dr Convertible (2.0L 4cyl Turbo 9A)
After owning five different Mercedes models over the past 10 years, I have returned to this one as my favorite of all time. The features that I appreciated 10 years ago are still there, but skill fully improved with updated technological capabilities. With so many vehicles growing larger and larger these days, it’s a joy to drive in the city, where parking space availability is minimal. … As important as that is, it’s also great fun to open up to the spaces of the long winding road on a warm sunny day!

Switched from years of owning 370Z Roadsters
Sharon Simmons, 03/25/2019
2019 Mercedes-Benz SLC-Class SLC 300 2dr Convertible (2.0L 4cyl Turbo 9A)
2019 - I love my new Benz!!! Switched from being a lifetime owner of 370Z Roadsters until the convertible didn't work on my last new one, so I went with the SLC 300 and never regretted it.
2022 -- STILL LOVING MY BENZ!!! My only complaint is they stopped making my gorgeous model the year after I purchased it. If they still sold this same type, I'd buy a NEW one! But I won't now.

2018 Merc SLC300 a traditional oldschool roadster
Brian, 03/10/2021
2018 Mercedes-Benz SLC-Class SLC 300 2dr Convertible (2.0L 4cyl Turbo 9A)
I'm a new convert to Mercedes, coming from a long line of BMW sedans and convertibles.
The interior is a pleasant place to be, getting in and out takes some gymnastics but the tradeoff is a classic british 60s roadster seating position with german engineering and quality.
The exterior improvements from the SLK gave the SLC a new lease on life, but the interior is essentially identical, … but still, average mercedes quality is better than the best Ford and Mazda can do with the mustang and Miata.
This is NOT a sports car, its got enough power to be enjoyable, but its not going to keep up with a modern BMW or Porche, it will however mess up your hair and make you smile a lot more than its german competition.
The technology in the car for a 2018 is compatible with my Ford F350, wifi hotspot, LED lights, Android Auto etc.
A hard top convertible is becoming hard to find and this car on the Californian mountain roads is its ideal home.. I can drive with the top down at anything over 55f and the neck heating keeps me warm enough to feel fine.
The car is eminently "chuckable" as you sit almost over the rear axle and is wonderful to take along the golden state's mountain roads, especially switchbacks and steep climbs in to wine country
I wouldnt own one of these without a warranty as I expect any repairs to be quite expensive and there's plenty that can go wrong with 2 turbos, a small engine and a lot of electronics, but I havent marked the car down for that.
The reason to drop a star is simply that the competition is so very strong and if youre looking for a sports car rather than a cruiser, there are better choices (BMW/Porche)
