Used 2023 Mercedes-Benz SL-Class for Sale near New Jersey

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

Prices are up 1.48% year-over-year — a sign of continued demand for this model year.

There are 300 listings available, which gives you a modest amount of inventory to compare before you buy.

If you find a listing below $86,409.73, 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 — 5/5 from users, and the expert rating is 7.33/10. The standout strength is Safety at 10/10.

The 2023 Mercedes-Benz SL-Class is built to make a statement as much as to serve as transportation, with striking styling, premium cabin materials, and strong performance. That makes it a fit if you want a high-end roadster 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 luxury-car mission comes through in its design and interior execution.

Only 28.7% of listings are priced as good or great deals, so the market is selective rather than broadly discounted.

Is the 2023 Mercedes-Benz SL-Class reliable?

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

This SL is positioned as a luxury grand touring roadster with premium materials and serious performance, which supports the sense that it is engineered to feel special over time. The expert evaluation also points to a car that is fast, composed, and capable of relaxed cruising in everyday driving.

Its performance notes emphasize strong acceleration, confident highway manners, and a chassis that can handle aggressive driving when you want it to. The cost-effectiveness notes also frame it as a more attainable way to access this nameplate than before, thanks to the addition of the more affordable SL 43.

For used buyers, the main long-term ownership risk is that the car’s high-end technology and complex controls can make upkeep and day-to-day use more demanding than in a simpler luxury car.

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

Accident-free inventory is excellent at 95% — clean inventory, standard diligence applies.

You should still run a history report and prioritize a pre-purchase inspection, especially on a car with this much technology and performance hardware. Focus on overall condition, because the cabin, controls, and convertible-top operation are all central to the ownership experience.

Key things to evaluate:

• Trim level: The lineup includes 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 already brings a premium, high-tech cabin, while the Performance versions add more track-oriented hardware and features.
• 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 AWD. It is quick, strong in aggressive driving modes, and tuned to feel like a cruiser in normal use.
• Safety package: The standard setup includes pop-up roll bars and Pre-Safe Sound, plus 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 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 one-year Mercedes Me subscription. The system can be distracting because of its touch-sensing controls and glare-prone screen.
• Fuel efficiency: The SL 55 averages 16 mpg in combined driving and returned 16.6 mpg on the testing 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 if you want the newest, most affordable way into the lineup and care most about getting the SL experience without stretching to the higher-performance versions.
• SL 55: This is the best-value trim if you want the strongest balance of power, luxury, and everyday usability. It brings the hand-built twin-turbo V8, AWD, and the core hardware that makes the car feel special.
• SL 63: Choose this if you want the most performance-focused version in the standard lineup and are willing to pay for the top-end experience.

The Driver Assistance Package is a worthwhile safety add-on if you want the most complete driver-assistance coverage.

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 have room to shop carefully rather than rush into the first car you see.

• Deal availability: 28.7% of listings are priced as good or great deals.
• Inventory: There are 300 listings available.
• Price trend: Prices are up 1.48% year-over-year.
• Clean inventory: 95.0% of listings are accident-free.

If you find a listing below $86,409.73, 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 $98,057 sits slightly above last year's $96,624.

That modest increase suggests the market has held up reasonably well for this model year. For a future seller, that kind of stability can help support confidence that the car is still desirable, especially if it remains in clean condition and presents well.

The year-over-year gain is not dramatic, but it does point to steady demand rather than a sharp drop in value. If you keep mileage reasonable and maintain the car carefully, you should be in a better position when it comes 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 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.

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:

• 28.7% of listings are priced as good or great deals.
• Accident-free inventory is excellent at 95% — clean inventory, standard diligence applies.
• Price trend: Prices are up 1.48% year-over-year.
• Owners rate it 5/5 — a strong satisfaction signal.
• This year stands out because the lineup adds the more affordable SL 43, giving you a lower entry point into the redesigned SL family.

The bottom line: If you want the strongest mix of style, performance, and a more attainable entry point into this generation, the 2023 is the one to target. If your priority is simply the lowest possible price, a nearby model year may be worth comparing, but the 2023’s broader lineup and solid market position make it the safer starting point.
