The 2019 Mercedes-Benz SLC, the final model year for the SLC designation in the US, is a compact luxury roadster with a distinctive retractable hardtop. It succeeded the beloved SLK-Class, carrying on its legacy of sophisticated open-air driving. Available primarily as the SLC 300 and the potent AMG SLC 43, it offered a new price range from approximately $48,000 to over $63,000. Its unique hardtop convertible design and blend of luxury with spirited performance made it stand out.
The Good

The 2019 Mercedes-Benz SLC offers engaging performance, especially the AMG 43 model's thrilling acceleration, appealing to emotional buyers. Its elegant design and luxurious interior provide exceptional comfort for a roadster. The retractable hardtop offers security and refinement, merging the practicality of a coupe with the joy of open-air driving. Decent efficiency for its class and Mercedes-Benz build quality contribute to its practical appeal and long-term value.

The Bad

Known weaknesses for the 2019 Mercedes-Benz SLC include its somewhat dated COMAND infotainment system with a smaller screen. Rear visibility is limited with the hardtop up, and cargo space is constrained, especially when the roof is down. Taller drivers may find the cabin snug, and the ride can be firm, particularly on AMG models. Expect higher maintenance and repair costs typical of a luxury convertible.

What Problems Does the 2019 Mercedes-Benz SLC Have?

For the 2019 Mercedes-Benz SLC, as the final model year of its lineage, many significant kinks from earlier generations were typically ironed out. However, being a low-volume luxury convertible, specific widespread "frequently reported problems" are less common than with high-volume vehicles. Generally, Mercedes-Benz vehicles exhibit good build quality, but potential owners should be aware of common luxury convertible concerns.

One primary area of attention for any retractable hardtop convertible, including the SLC, is the complex roof mechanism. While generally robust, components like sensors, hydraulic lines, motors, and seals can develop issues over time, leading to operational glitches or leaks. These repairs can be costly due to specialized parts and labor.

Electrical issues, although not rampant, can manifest as infotainment glitches, sensor failures, or battery drain, typical of cars with extensive electronic systems. The 2019 model still used Mercedes's older COMAND interface, which, while reliable, could sometimes experience minor software hiccups.

Suspension components, particularly on the sportier AMG SLC 43, may show accelerated wear on bushings, shocks, and mounts due to performance driving or rough road conditions. Brake wear can also be more pronounced on the AMG variant.

Minor oil leaks, often from valve covers or seals, are not uncommon on higher-mileage Mercedes-Benz engines across various models, and while not critical immediately, should be addressed to prevent larger issues. Transmission issues are rare with proper maintenance, but fluid changes are critical for longevity.

Regarding recalls, the 2019 SLC had a few minor recalls, consistent with many vehicles. For instance, some vehicles might have been subject to recalls related to the emergency call system software or the power steering control unit. It is always crucial for prospective buyers to check the NHTSA website using the specific vehicle's VIN for any open recalls that need to be addressed.

Long-term reliability, assuming diligent maintenance, is generally good. However, the costs associated with specialized parts and labor for a luxury performance car mean that any out-of-warranty repairs can be substantial. Owners who adhere to the recommended service schedule and address minor issues promptly will likely experience better long-term durability, but budgeting for higher service costs is essential.

How long will the 2019 Mercedes-Benz SLC last?

With diligent maintenance, a 2019 Mercedes-Benz SLC can reliably serve its owners for 150,000 to 200,000 miles, or 10-15+ years. As a niche luxury roadster, many SLCs are driven as secondary or weekend vehicles, potentially leading to lower average mileage accumulation compared to a daily driver sedan. The powertrains (both the 2.0L turbo and 3.0L biturbo) are generally robust, and the chassis is well-engineered for durability.

However, long-term weaknesses can emerge. The complex retractable hardtop mechanism's seals, sensors, and hydraulic components can degrade, leading to potential leaks or operational failures over time. Electrical gremlins, common in many modern luxury cars, might surface as the vehicle ages. Interior materials like leather or MB-Tex generally hold up well, but minor trim rattles or wear could occur. Suspension components will inevitably require replacement. Regular, specialized Mercedes-Benz maintenance is paramount to achieving maximum service life and mitigating costly long-term issues.

What Technology & Safety Features are Included?

The 2019 Mercedes-Benz SLC, while offering a luxurious experience, featured technology that was beginning to show its age compared to newer Mercedes models. Its built-in infotainment system was the COMAND interface, displayed on a 7-inch central screen. Standard entertainment features included an AM/FM radio, HD Radio, Bluetooth phone and audio streaming, and two USB ports. Optional upgrades included a COMAND navigation system, which integrated into the existing display, and a premium Harman Kardon Logic7 surround-sound audio system for enhanced acoustic quality. While Apple CarPlay and Android Auto were available, they were often part of optional packages or required a specific Multimedia Package.

For driver-assistance and safety, the SLC came standard with several core Mercedes-Benz technologies. These included ATTENTION ASSIST, which monitors driver behavior for signs of drowsiness; Adaptive Brake technology with a HOLD function for convenience; and the PRE-SAFE system, which prepares the vehicle for an impending collision by tightening seatbelts and adjusting seats. Standard passive safety features included multiple airbags (front, side, head/thorax), anti-lock brakes (ABS), traction control, stability control, and sturdy roll-over protection bars behind the seats.

Numerous advanced driver-assistance features were available as options, often bundled into packages. These included Blind Spot Assist, which warns the driver of vehicles in adjacent lanes; Lane Keeping Assist, which helps prevent unintentional lane departures; and PARKTRONIC with Advanced Parking Assist, aiding in parallel and perpendicular parking maneuvers. A rearview camera was a standard inclusion, crucial for visibility in a compact roadster.

Regarding crash-test ratings, it's common for low-volume, niche sports cars like the Mercedes-Benz SLC to not undergo full crash testing by major organizations such as the National Highway Traffic Safety Administration (NHTSA) or the Insurance Institute for Highway Safety (IIHS). The high cost and limited sales volume typically mean that comprehensive crash-test ratings are not available for these specific models. However, Mercedes-Benz maintains a strong reputation for safety engineering, incorporating robust structural designs and comprehensive passive safety systems across its entire lineup.

2019 Mercedes-Benz SLC Prices and Market Value

When new in 2019, the Mercedes-Benz SLC 300 had a starting MSRP of approximately $48,950, while the performance-oriented AMG SLC 43 began around $63,900, with options quickly pushing prices higher.

On the current used market (as of mid-2024), a 2019 SLC 300 typically ranges from $25,000 to $35,000, depending heavily on mileage, condition, and optional packages. The AMG SLC 43 models command higher prices, generally between $35,000 and $45,000 or more.

Like most luxury vehicles, especially convertibles, the SLC experienced significant depreciation from its new price. However, as it was the final year of the SLC/SLK lineage and represents a distinct segment (hardtop roadster), its depreciation has likely stabilized compared to more common sedans. Factors affecting resale value include overall condition, mileage, complete service history, desirable option packages (e.g., Premium Package, AMG Line styling), and regional demand for luxury convertibles. A well-maintained, lower-mileage example with sought-after features will command a premium.

2019 Mercedes-Benz SLC Cost of Ownership

The 2019 Mercedes-Benz SLC is a costly vehicle to own. Insurance premiums are higher than average due to its luxury brand, convertible body style, and performance capabilities, with the AMG SLC 43 being even more expensive. Both models require premium unleaded fuel, contributing to higher running costs. Maintenance is significantly more expensive than average; Mercedes-Benz scheduled services (e.g., A/B service) involve specialized labor and parts. Unexpected repairs, particularly for the complex retractable hardtop or specialized AMG components, can be very costly. Long-term ownership demands a substantial budget for upkeep, making it anything but economical. Prospective buyers must factor in these elevated ongoing expenses.

2019 Mercedes-Benz SLC Insurance

Insurance for a 2019 Mercedes-Benz SLC is moderately priced, reflecting its status as a Convertible with strong safety ratings and
reasonable repair costs.

How Does the 2019 Mercedes-Benz SLC Compare to Other Convertible?

The 2019 Mercedes-Benz SLC operates in a competitive segment of compact luxury roadsters, stacking up against formidable rivals like the Porsche 718 Boxster, BMW Z4, and Audi TT Roadster.

In terms of performance, the SLC 300 offers a spirited, comfortable drive, but isn't as dynamically sharp or engaging as a Porsche 718 Boxster. The AMG SLC 43, however, brings strong acceleration and a fantastic exhaust note, putting it in direct competition with the BMW Z4 M40i. The Boxster generally offers superior handling and a more visceral driving experience across its lineup. The Audi TT Roadster, while agile, is less about raw power and more about refined, all-weather performance with its Quattro system.

For features, the SLC provides a luxurious cabin with Mercedes-Benz prestige. However, its COMAND infotainment system, while functional, felt a bit dated in 2019 compared to the BMW Z4's iDrive 7.0 or Audi TT's innovative Virtual Cockpit. The SLC's unique selling point is its retractable hardtop, offering better sound insulation and security than the soft-tops of its rivals.

Reliability is generally on par with other German luxury brands; with proper maintenance, all these vehicles can be dependable. Mercedes-Benz and BMW typically have similar ownership costs, which are higher than average. Porsche enjoys a reputation for strong mechanical reliability, though parts can be expensive.

Pricing, especially on the used market, often makes the SLC a relatively strong value proposition. While new, it was priced competitively, its depreciation curve can make it a more accessible entry into the luxury roadster segment than a comparable Boxster, which tends to hold its value exceptionally well.

Recommended Alternatives:
  • Porsche 718 Boxster: For the ultimate driving enthusiast prioritizing precision, handling, and a more engaging experience, the Boxster remains the benchmark, albeit at a higher price point, especially on the used market.
  • BMW Z4 (G29): The 2019-generation Z4 is a very strong competitor, offering more modern technology, a fresh design, and excellent performance (especially the M40i variant), making it a compelling alternative for those seeking up-to-date features and comparable power.
  • Audi TT Roadster: A stylish and tech-forward option with the Virtual Cockpit, appealing to those who prioritize design and advanced digital displays, though its performance character is distinct from the rear-wheel-drive focused SLC.
  • Jaguar F-Type Convertible: For buyers seeking a more grand touring experience with stunning looks and powerful engine options, the F-Type offers a different flavor of luxury sports car, often at a higher price point.

Final Verdict: Is the 2019 Mercedes-Benz SLC a Good Convertible?

The 2019 Mercedes-Benz SLC is ideal for buyers seeking a compact, luxurious hardtop convertible with Mercedes-Benz pedigree. It suits individuals who prioritize a blend of refined open-air motoring, comfortable cruising, and sufficient performance for spirited drives, rather than outright track capability. It's perfect for weekend escapades or as a stylish second car, appealing to those who appreciate the security and quietness of a retractable hardtop over a traditional soft-top.

It is absolutely worth buying, but under specific conditions. Firstly, definitely buy it used; its new price depreciation was substantial, offering excellent value on the secondary market. The SLC 300 trim provides a superb balance of performance, luxury, and relative fuel efficiency, making it a smart choice for most. Opt for the AMG SLC 43 if maximum performance and a more aggressive character are paramount, but be prepared for higher running costs. Crucially, any purchase should be contingent on a thorough pre-purchase inspection by a Mercedes-Benz specialist, and the buyer must be prepared for the elevated maintenance and repair costs inherent with a luxury convertible. If these conditions are met, the SLC offers a unique and enjoyable ownership experience.
