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 282 listings available, which gives you a modest amount of inventory to compare before you buy. If you find a listing below $86,452.13, 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 — the 5/5 user rating points to strong owner satisfaction, and the expert rating is 7.33/10. The standout strength is Safety at 10/10.

The SL-Class is built to make a statement, with striking styling, premium cabin materials, and serious performance that fits its high-end roadster mission. The trade-offs are clear: the infotainment system can be aggravating, fuel economy is poor, and cargo space is limited.

Those compromises matter most if you want a luxury convertible that is easy to live with every day. If you care more about presence, power, and a richly finished interior than about practicality, this model year fits that brief well.

The market shows 29.4% 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.

This SL-Class is positioned as a premium grand touring roadster, and the overview emphasizes a strong blend of luxury, performance, and distinctive design. The expert evaluation also points to a car that feels special to drive, with a powerful engine and a cabin that delivers quality and modernism.

The performance notes suggest the car is built for confident, high-speed driving, with a robust drivetrain and hardware that supports both comfort and spirited use. The cost-effectiveness commentary also notes that the addition of the more affordable SL 43 model gives the lineup more value than last year.

For used buyers, the main long-term ownership risk is that the car’s high-end complexity and premium positioning can make any repair or upkeep issue more expensive than you might expect.

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

Accident-free inventory is excellent at 96.1% — clean inventory, standard diligence applies.

You should still run a vehicle history report and prioritize a pre-purchase inspection, especially because this is a complex luxury convertible with advanced electronics and a power-folding roof. Pay close attention to the condition of the infotainment system, touch controls, and any driver-assistance features, since those are the kinds of systems that can affect day-to-day satisfaction. It also makes sense to inspect the cabin, roof operation, and overall cosmetic condition carefully, because this car’s appeal depends heavily on how well it presents.

Key things to evaluate:

• Trim level: The SL lineup includes the SL 43, SL 55, and SL 63, all in standard Touring trim. The SL 55 and SL 63 can also be had with Performance trim, and the base setup does not include the extra performance hardware that comes with that upgrade.
• 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 and AWD. It is quick, and the performance tuning adds driving modes that let you tailor the car’s behavior.
• Safety package: The standard setup includes pop-up roll bars, Pre-Safe Sound, and 10 airbags. 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 11.9-inch portrait touchscreen with MBUX, wireless Apple CarPlay and Android Auto, wireless smartphone charging, and a digital assistant. It also includes a 12.3-inch digital instrument display and over-the-air-style connected services through Mercedes Me.
• Fuel efficiency: The SL 55 averages 16 mpg in combined driving and returned 16.6 mpg on the test loop. It burns premium fuel, and the overview also calls fuel economy poor.

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:

• Base trim: The SL 43 is the entry point, and the broader SL setup still leans heavily on touch-based controls and a complex infotainment interface, so you are not buying a simple or especially easy-to-use luxury convertible.
• Sweet-spot trim: The SL 55 is the most compelling choice if you want the core SL experience, because it combines the strong V8 powertrain with the luxury, performance, and standard safety hardware that define the model.
• Premium/top trim: The SL 63 is the top performance choice if you want the most aggressive version of the lineup, but the SL 55 already delivers a lot of the appeal without pushing as far up the price ladder.

The Driver Assistance Package is a worthwhile safety-package add-on if you want more advanced driver assistance.

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

This looks like a moderate, selective buyer’s market, so you can shop carefully and still find worthwhile opportunities.

• Deal availability: 29.4% of listings are priced as good or great deals.
• Inventory: There are 282 listings available.
• Price trend: Prices have held steady compared with last year.
• Clean inventory: 96.1% of listings are accident-free.

If you find a listing below $86,452.13, 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 $98,440 sits slightly below last year's $99,174.

That small decline suggests the market has been relatively stable rather than sharply weakening. For a future seller, that kind of movement can be reassuring because it points to a model that is holding value in a predictable way instead of swinging wildly.

The year-round range also shows that buyers are still willing to pay near the top end for the right example. If your car is well kept, well equipped, and presented cleanly, you should have a better chance of attracting serious interest when it is time to sell.

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 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 and lane-centering systems worked well in some conditions, but they seemed less sure of themselves in brighter light. The lane-keeping assist is also quite decisive, which can be helpful when you need it and irritating when you do 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:

• 29.4% of listings are priced as good or great deals.
• Accident-free inventory is excellent at 96.1% — 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 stands out for the addition of the more affordable SL 43, which broadens the lineup’s value.

The bottom line: If you want the strongest mix of style, performance, and value in this generation, the 2023 is a sensible target. If you are especially price-sensitive, you may want to compare it with nearby model years and focus on the best-equipped example you can find at the lowest clean-history price.
