How much does the 2023 Mercedes-Benz SL-Class cost?

Prices are up 3.59% year-over-year — a sign of continued demand for this model year.

Is the 2023 Mercedes-Benz SL-Class a good car?

Yes — the 2023 Mercedes-Benz SL-Class earns a 5/5 user rating and a 7.33/10 expert rating.

The standout strength is Safety at 10/10.

It stands out as a luxury grand tourer with striking styling and premium interior materials, and it is meant to feel special from the moment you see it and sit in it. The trade-offs are clear: the infotainment system is aggravating, fuel economy is poor, and cargo space is limited.

The market still shows some room to shop, with 32.6% of listings marked as good or great deals.

Is the 2023 Mercedes-Benz SL-Class reliable?

Owners rate it 5/5, a strong signal of long-term satisfaction.

The 2023 SL-Class is presented as a high-end grand tourer that blends luxury, performance, and technology, but it also brings everyday irritations that can affect ownership satisfaction. The expert evaluation also notes that the car is designed to be fast and special, while still feeling like a cruiser in normal driving.

Its performance setup is described as strong and capable, with a hand-built twin-turbocharged 4.0-liter V8, all-wheel drive, and a nine-speed automatic transmission. Mercedes also includes a standard surround-view camera system, parking sensors, and active semi-autonomous parking assist, which helps offset the car’s poor rear visibility.

Mercedes also includes a complimentary one-year subscription to Mercedes Me connected services with access to a Wi-Fi hotspot and online music streaming.

For a used buyer, the main long-term risk is that the car’s high-tech controls and complex systems may be more frustrating to live with than a simpler luxury convertible.

What should I look for when buying a used 2023 Mercedes-Benz SL-Class?

Accident-free inventory is excellent at 93.8% — clean inventory, standard diligence applies.

You should still run a vehicle history report and prioritize a pre-purchase inspection, especially because this car’s appeal depends so much on condition, technology, and overall presentation. Focus on how well the cabin, infotainment, and convertible-top operation work, since those are the kinds of features that can make or break the ownership experience.

Key things to evaluate:

• Trim level: The SL lineup includes the SL 43, SL 55, and SL 63, all in standard Touring trim, with Performance trim available for the SL 55 and SL 63. The cabin is described as luxurious and high-tech, but the touch-sensing controls can hurt day-to-day satisfaction, so base-spec simplicity is not really the point here.
• Powertrain: The SL 43 uses a four-cylinder engine with an electric turbocharger and makes 375 horsepower and 354 pound-feet of torque. The SL 55 uses a hand-built, twin-turbocharged 4.0-liter V8 with 469 horsepower and 516 pound-feet of torque, paired with a nine-speed automatic transmission and all-wheel drive.
• Safety package: The standard setup includes pop-up roll bars, Pre-Safe Sound, and 10 airbags. The Driver Assistance Package adds 13 systems, including adaptive cruise control with lane-centering assist and lane-change assist, active emergency stop assist, and active braking for intersections, cross-traffic, and sudden congestion situations.
• Infotainment: The cabin uses a 12.3-inch digital instrumentation screen and an 11.9-inch portrait touchscreen with MBUX, wireless Apple CarPlay and Android Auto, wireless smartphone charging, and a one-year Mercedes Me subscription. The system is also described as glare-prone and fingerprint-prone, with touch controls that can be distracting.
• Fuel efficiency: The SL 55 averages 16 mpg in combined driving and returned 16.6 mpg on the test loop.

Which 2023 Mercedes-Benz SL-Class trim should I buy?

The 2023 Mercedes-Benz SL-Class is offered in 3 trim levels: SL 43, SL 55, SL 63.

Here's the short version:

• SL 43: This is the entry point, and it brings the new four-cylinder engine with an electric turbocharger plus the core SL design and luxury focus. It makes the most sense if you want the look and feel of the car without stretching to the higher-output V8 models.
• SL 55: This is the best-value choice for most shoppers because it adds the hand-built twin-turbo V8, stronger performance, and the more complete version of the SL experience without jumping all the way to the top model.
• SL 63: This is the most powerful and most expensive choice, so it suits you if you want the highest-performance version and are willing to pay for it.

The Driver Assistance Package is a worthwhile safety option, and it adds 13 additional systems.

Is now a good time to buy a used 2023 Mercedes-Benz SL-Class?

This looks like a moderate market for selective buyers, with enough inventory to shop carefully but not so much that you should expect deep discounts everywhere.

• Deal availability: 32.6% of listings are priced as good or great deals.
• Inventory: There are 304 listings available.
• Price trend: Prices are up 3.59% year-over-year.
• Clean inventory: 93.8% of listings are accident-free.

If you find a listing below $86,464, that's toward the low end of the year-round range and worth acting on quickly.

What is the 2023 Mercedes-Benz SL-Class's resale value?

The current average of $97,750 sits slightly above last year's $94,362.

That upward move suggests the market is still willing to pay for this model year, which is a positive sign if you plan to sell later. The year-over-year increase also points to steady demand rather than a softening market.

Because the SL-Class combines luxury appeal with strong performance, it should continue to attract shoppers who want a statement car. Vehicles with strong owner satisfaction ratings, like this model year's 5/5, tend to retain buyer demand, which supports resale value over time.

Is the 2023 Mercedes-Benz SL-Class safe?

The 2023 Mercedes-Benz SL-Class earns a 10/10 safety score from our experts.

It comes with standard pop-up roll bars, Pre-Safe Sound, and 10 airbags. The Driver Assistance Package adds 13 additional safety and driver-assistance systems, including adaptive cruise control with lane-centering assist and lane-change assist, active emergency stop assist, and active braking for intersections, cross-traffic, and sudden congestion situations.

The lane-keeping and lane-centering systems worked well in some conditions but seemed less sure of themselves in brighter light, so you should test them carefully if you plan to rely on them often. The lane-keeping assist system is also described as decisive, which can be helpful when it intervenes correctly but irritating when it does not.

Should I buy a 2023 Mercedes-Benz SL-Class or consider a different year?

If you're weighing the 2023 against nearby model years, here's how to think about it:

Choose the 2023 if:

• 32.6% of listings are priced as good or great deals.
• Accident-free inventory is excellent at 93.8% — clean inventory, standard diligence applies.
• Price trend: Prices are up 3.59% year-over-year.
• Owners rate it 5/5 — a strong satisfaction signal.
• The 2023 model adds the more affordable SL 43, which broadens the lineup and gives you a lower entry point into the SL family.

The bottom line: If you want this generation of SL with strong demand, solid satisfaction, and a broader range of choices, the 2023 is the one to target. If your priority is simply finding the lowest possible price, a nearby year may be worth comparing, but the 2023 gives you a compelling mix of inventory, pricing momentum, and model-year appeal.
