Used 2023 Mercedes-Benz SL-Class for SaleNationwide

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

Prices are up 4.56% year-over-year — a sign of continued demand for this model year.

There are 312 listings available, which gives you a modest amount of inventory to compare.

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 7.3/10. The standout strength is Safety at 10/10.

The 2023 Mercedes-Benz SL-Class is built to make a statement, with stylish design and premium interior materials standing out as major strengths. It also brings a powerful engine and a high-end cabin, which fits buyers who want a luxurious roadster with strong visual presence and a sense of occasion.

The trade-offs are clear: the infotainment system is aggravating, fuel economy is poor, and cargo space is limited. Even so, if you want a glamorous grand tourer that blends luxury and performance, this year’s SL-Class fits that use case well.

29.5% of listings are priced as good or great deals, which suggests there are still some attractive opportunities if you shop carefully.

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 high-end, technology-rich grand tourer, and the expert review emphasizes that it delivers a premium cabin and strong performance. It also notes that the car can feel soft and lazy in Comfort mode, then much more focused in more aggressive settings, which suggests a broad operating range rather than a narrow one.

The performance writeup also says the car is “mighty fast” in aggressive driving modes and “supports intensely focused driving,” which is a good sign for buyers who want a car that feels engineered rather than merely styled. If you’re buying used, the main long-term risk is that its complex controls and high-end systems can make ownership less forgiving if prior maintenance or repairs were neglected.

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

Accident-free inventory is excellent at 94.2% — 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 a lot of electronic and mechanical systems. Focus on overall condition, how the controls operate, and whether the car’s premium features work as intended. Pay close attention to signs of wear in the cabin and any evidence that the roof, infotainment, or driver-assistance systems have been troublesome.

Key things to evaluate:

• Trim level: The 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 base setup emphasizes style, luxury, and a high-end cabin, while the more expensive versions add more aggressive hardware and equipment.
• 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 all-wheel drive. Mercedes says it can reach 60 mph in 3.8 seconds and averages 16 mpg in combined driving.
• Safety package: The standard safety equipment includes pop-up roll bars and Pre-Safe Sound, and the available Driver Assistance Package adds 13 additional safety and driver-assistance systems. Highlights include 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 MBUX, 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 access.
• Fuel efficiency: The SL 55 averages 16 mpg in combined driving, and the expert review notes that fuel economy is 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:

• SL 43: This is the entry point and the value-oriented choice if you want the SL experience with the lowest starting price in the lineup. It gives you the core design, luxury, and technology themes without moving up to the more expensive performance-focused versions.
• SL 55: This is the best-value trim if you want the strongest balance of performance and equipment. It brings the hand-built twin-turbo V8, all-wheel drive, and the broadest mix of grand-touring comfort and serious speed.
• SL 63: Choose this if you want the most powerful and most expensive version of the standard gas lineup. It suits you best if outright performance matters more than value.

The Driver Assistance Package is a reasonably priced option, and it adds 13 additional safety and driver assistance systems.

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

This is a seller’s market, so you should act selectively and be ready to move when a well-priced listing appears.

• Deal availability: 29.5% of listings are priced as good or great deals.
• Inventory: There are 312 listings available.
• Price trend: Prices are up 4.56% year-over-year.
• Clean inventory: 94.2% of listings are accident-free.

If you find a listing below $86,410, 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 $95,285 sits slightly above last year's $91,133.

That upward move suggests the market has held up well for this model year, which is a positive sign if you plan to sell later. A price increase like this usually means buyers still see value in the car’s mix of style, luxury, and performance. If demand stays steady, that can help support resale strength over time.

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 earns a strong safety setup with standard pop-up roll bars and Pre-Safe Sound, plus 10 airbags. The available 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 review also notes that the lane-keeping and lane-centering systems can seem less sure of themselves in bright sunlight, so you should test those features carefully on a used example. Even so, the overall safety package is a major strength for this model year.

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:

• 29.5% of listings are priced as good or great deals.
• Accident-free inventory is excellent at 94.2% — clean inventory, standard diligence applies.
• Price trend: Prices are up 4.56% year-over-year.
• Owners rate it 5/5 — a strong satisfaction signal.
• This year adds the more affordable SL 43, which broadens the lineup and improves value.

The bottom line: The 2023 is a strong choice if you want the updated SL formula with a broader lineup and solid market support. If you’re especially price-sensitive, you may want to shop carefully for the right listing, but the 2023 stands out as the better-balanced pick for most used buyers.
