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

Prices have held steady compared to this time last year, signaling a stable and predictable market for this model year.

There are 296 listings available, which gives you a modest amount of inventory to compare before you buy. If you find a listing below $86,426.50, that's toward the low end of the year-round range and worth acting on quickly.

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

Yes — it earns a 5/5 user rating and a 7.33/10 expert rating. The standout strength is Safety at 10/10.

The 2023 SL-Class is built to make a statement, with striking styling, premium cabin materials, and strong performance that fit its luxury-roadster mission. It also brings a richly finished interior and serious power, which makes it especially appealing if you want a high-end convertible that feels special every time you drive it.

The trade-offs are clear: the infotainment system can be aggravating, fuel economy is poor, and cargo space is limited. Even so, the car’s combination of design, luxury, and performance gives it a distinctive role if you want presence as much as transportation.

The market shows 27.4% of listings as good or great deals, so there is some room to shop selectively.

Is the 2023 Mercedes-Benz SL-Class reliable?

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

The SL-Class is presented as a premium grand touring convertible with a strong emphasis on quality, class, and modernism. Its performance setup is substantial, and the car is described as fast, composed, and rewarding when you drive it hard, which supports the sense that it is engineered to deliver a high-end ownership experience.

Mercedes also includes a complimentary one-year subscription to Mercedes Me connected services with access to a Wi-Fi hotspot and online music streaming, which adds some ownership convenience. For used buyers, the main long-term risk is that the car’s complex technology and touch-heavy controls could create more frustration 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 95.3% — clean inventory, standard diligence applies.

You should still run a history report and verify that the car’s equipment and condition match the listing, especially on a model with a lot of technology and luxury features. A pre-purchase inspection is worth prioritizing so you can check the infotainment system, roof operation, and any signs of wear in the cabin or exterior. Focus on how well the car’s controls, electronics, and convertible hardware work in real use.

Key things to evaluate:

• Trim level: The redesigned SL has a more dramatic body, a fabric soft top, and a cabin that Mercedes describes as hyper-analog, but the touch-sensing controls can reduce satisfaction. The base setup also lacks some of the extra equipment found on the more heavily optioned test car, so you should pay close attention to which convenience and appearance features are included.
• Powertrain: 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. It is quick, strong in aggressive driving modes, and tuned to feel fast without losing its grand-touring character.
• Safety package: The standard setup includes pop-up roll bars, Pre-Safe Sound, 10 airbags, a surround-view camera system, parking sensors, and active semi-autonomous parking assist. The Driver Assistance Package adds 13 more 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 instrument display and an 11.9-inch portrait touchscreen with wireless Apple CarPlay and Android Auto, wireless smartphone charging, and a digital assistant. The system also supports over-the-air-style connected services through Mercedes Me, but the display can suffer glare and fingerprints.
• 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 the value-oriented choice if you want the newest SL experience at the lowest price. It gives you the redesigned body, the luxury-roadster image, and the latest cabin tech without moving up to the more expensive performance-focused versions.
• SL 55: This is the best-value trim for most buyers because it combines the strongest balance of power, luxury, and everyday usability. It adds the hand-built twin-turbo V8, all-wheel drive, and the kind of performance that makes the SL feel genuinely special.
• SL 63: Choose this if you want the most performance-oriented version and are willing to pay for the top end of the lineup. It is the most powerful standard gas trim mentioned here and suits you best if outright speed matters more than value.

The Driver Assistance Package is a worthwhile safety option if you want more advanced driver-assistance features.

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

This is a moderate market for selective buyers, so you can shop carefully without expecting a deep bargain on every listing.

• Deal availability: 27.4% of listings are priced as good or great deals.
• Inventory: There are 296 listings available.
• Price trend: Prices have held steady compared with last year.
• Clean inventory: 95.3% of listings are accident-free.

If you find a listing below $86,426.50, 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 $98,662 sits slightly below last year's $99,457.

That small decline suggests the market has been relatively stable rather than sharply weakening. For a future seller, that can be a good sign because it points to predictable pricing instead of a sudden drop in value.

The SL-Class also benefits from strong desirability as a luxury roadster with premium materials and serious performance. 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?

It earns a 10/10 safety score from our experts.

Among the SL’s standard safety features, two of the more unusual items are pop-up roll bars that help to protect occupants in a rollover accident and Pre-Safe Sound. That latter technology emits a “pink noise” immediately prior to a collision that helps protect your hearing from the sounds of the impact, including the deployment of the SL’s 10 airbags.

A Driver Assistance Package is a reasonably priced option, and it adds 13 additional safety and driver assistance systems. Highlights include adaptive cruise control with lane-centering assist and lane-change assist, an active emergency stop assist system, and active braking for intersections, cross-traffic, and sudden congestion situations.

The lane-keeping system is decisive, which can be helpful when it correctly detects an unintended lane departure. If it intervenes when you do not want it to, though, it can feel intrusive.

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:

• 27.4% of listings are priced as good or great deals.
• Accident-free inventory is excellent at 95.3% — clean inventory, standard diligence applies.
• Price trend: Prices have held steady compared with last year.
• Owners rate it 5/5 — a strong satisfaction signal.
• This year benefits from the addition of the more affordable SL 43 model, which broadens the lineup and improves value.

The bottom line: If you want the strongest mix of style, performance, and value in this generation, the 2023 is the one to target. If you are especially price-sensitive, you can still shop nearby years, but the 2023 stands out because it combines stable pricing, strong satisfaction, and a broader lineup than before.
