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

Prices have softened 12.26% compared to this time last year, making it a favorable time to shop this model year.

There are 1,220 listings available, which gives you a meaningful amount of inventory to compare.

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

The 2023 Mercedes-Benz S-Class earns an 8.5/10 expert rating.

The model scores 9/10 across Look and feel, Performance, Technology, and Safety.

You’re looking at a luxury full-size sedan that emphasizes premium materials, strong performance, and advanced technology. The 2023 update adds a new powertrain, and the plug-in hybrid setup gives you a modern electrified option with substantial electric driving range.

The trade-offs are clear: it’s very expensive, and it doesn’t qualify for a federal tax rebate. Those drawbacks matter most if you’re comparing it against other luxury sedans on value rather than on features or prestige.

With 32.7% of listings marked as good or great deals, you do have some room to shop selectively.

Is the 2023 Mercedes-Benz S-Class reliable?

The 2023 Mercedes-Benz S-Class is presented as a polished, technically advanced luxury sedan, and its powertrain is described as smooth and seamless in normal driving. The hybrid system transitions cleanly between electric and gas power, and the nine-speed automatic generally stays out of the way.

The performance notes also point to a few ownership realities you should keep in mind. The powertrain is excellent, but there’s a slight jerk at times when the transmission downshifts into first gear at lights, and the car’s complexity means long-term upkeep can be more demanding than on a simpler sedan.

You also get a maintenance perk with the hybrid battery warranty coverage, which helps offset some ownership concern. For used buyers, the main long-term risk is that a high-tech flagship like this can be costly to maintain once it’s out of warranty.

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

Accident-free inventory is solid at 89.3% — always verify the vehicle history report.

You should still check the history report carefully, because a clean listing percentage doesn’t replace a proper records review. Prioritize a pre-purchase inspection that focuses on the hybrid system, electronics, suspension, and any optional equipment, since this is a highly complex luxury sedan. Pay close attention to condition, because repair costs can rise quickly if previous owners skipped maintenance or if premium features aren’t working properly.

Key things to evaluate:

• Trim level: The standard S-Class emphasizes calm sophistication, while the tester’s optional high-gloss black trim, 20-inch AMG wheels, and AMG-style bumpers make it look less staid. The interior is a major strength, with eight leather colors, five trim materials, and superb fit and finish.
• Powertrain: The S 580e pairs a 3.0-liter turbocharged inline-six with a 28.6-kWh battery and electric motor. It delivers 56 miles of all-electric range, 51 MPGe combined, 510 horsepower, and 553 lb-ft of torque.
• Safety package: The car includes lane-keep assist, blind-spot monitoring, automatic emergency braking, rear cross-traffic alert, hands-on highway driver assist, Crosswind Assist, and Speed Limit Assist. The hands-on system can handle lane centering and lane changes when you signal.
• Infotainment: You get a 12.3-inch digital gauge cluster and a 12.8-inch OLED center touchscreen with MBUX, wireless Apple CarPlay, wireless Android Auto, augmented-reality navigation, wireless charging, and a standard Burmester sound system.
• Fuel efficiency: The plug-in hybrid is rated at 51 MPGe combined, and the gas engine returns 23 mpg combined when the battery is depleted. The review also notes 56 miles of electric range and a total range of 470 miles.

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

The 2023 Mercedes-Benz S-Class is offered in 4 trim levels: S 500, S 580, Maybach S 580, and Maybach S 680.

Here's the short version:

• S 500: This is the entry point if you want the S-Class experience with the least expensive path into the lineup. It should suit you if you care most about the core luxury, technology, and flagship feel rather than the most elaborate powertrain or prestige trim.
• S 580: This is the better choice if you want more performance and a stronger luxury setup without stepping all the way into Maybach territory. It’s the trim to focus on if you want the best balance of capability and value in the lineup.
• Maybach S 580: Choose this if you want a more exclusive, chauffeur-style version of the S-Class with a stronger emphasis on luxury presence and rear-seat appeal.
• Maybach S 680: This is the top-end choice for buyers who want the most lavish and prestigious version of the S-Class lineup.

The safety package is especially comprehensive, and the hands-on highway driver-assist system is a standout feature to look for.

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

This is a moderate market for selective buyers, so you can shop carefully and still find worthwhile listings.

• Deal availability: 32.7% of listings are priced as good or great deals.
• Inventory: There are 1,220 listings available.
• Price trend: Prices have softened 12.26% compared with last year.
• Clean inventory: 89.3% of listings are accident-free.

If you find a listing below $77,816, that's toward the low end of the year-round range and worth acting on quickly.

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

The current average of $78,407 sits slightly below last year's $89,366.

That drop suggests the market has moved in your favor if you’re buying now, but it also means future resale values may remain sensitive to broader luxury-sedan pricing trends. If you plan to sell later, the S-Class’s strong brand appeal should help, but depreciation can still be meaningful because this is a high-priced flagship.

For a future seller, the key is to buy well and keep the car in excellent condition. A lower entry price today can help cushion depreciation, especially if you choose a desirable trim and maintain the vehicle carefully.

Is the 2023 Mercedes-Benz S-Class safe?

The 2023 Mercedes-Benz S-Class has not yet been rated by the National Highway Traffic Safety Administration or the Insurance Institute for Highway Safety.

It earns a 9/10 safety score from our experts.

The safety equipment is extensive, with lane-keep assist, blind-spot monitoring, automatic emergency braking, rear cross-traffic alert, hands-on highway driver assist, Crosswind Assist, and Speed Limit Assist. The hands-on system can keep the car centered, maintain distance, and even handle lane changes when you signal.

That said, the lack of crash-test ratings means you’re relying on the car’s strong active-safety hardware and the brand’s engineering reputation rather than published test results.

Should I buy a 2023 Mercedes-Benz S-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:

• 32.7% of listings are priced as good or great deals.
• Accident-free inventory is solid at 89.3% — always verify the vehicle history report.
• Price trend: Prices have softened 12.26% compared with last year.
• The 2023 adds a new plug-in hybrid powertrain with strong electric range and modern charging flexibility.

Consider the 2022 if:

• At $63,247, the 2022 costs less than the current year's $78,407 average.
• It offers a polished full-size luxury sedan setup with mild-hybrid powertrains and all-wheel drive.

The bottom line: If you want the newer electrified powertrain, stronger tech story, and a more modern S-Class setup, the 2023 is the better target. If your priority is spending less up front, the 2022 is the smarter value play and still delivers the flagship luxury experience.
