Should I buy a used Mercedes-Benz SL-Class now or wait for the next model?

Buy now if:

• Price trend: The 2022 model is at −1.61% versus a year ago, and the 2017 model is at −7.38%.
• Deal availability: The 2022 model has 28.7% good and great deals.
• Sweet-spot year: The 2023 model has the most listings at a current average price of $98,057. The Mercedes-Benz SL-Class offers a blend of style, luxury, and performance that makes it feel special every time you drive it.

Consider waiting if:

• Powertrain/efficiency: Mercedes offers no shortage of powertrains with the SL, all with a nine-speed dual-clutch automatic transmission. The base AMG SL 43 has a 2.0-liter turbocharged inline-four, which might not seem worthy of the brand's flagship convertible, but it develops 416 horsepower and 369 pound-feet of torque, taking the rear-wheel drive (RWD) SL 43 from 0–60 mph in a claimed 4.6 seconds.
• Tech: The SL’s third-generation Mercedes-Benz User Experience (MBUX) infotainment system incorporates wireless Apple CarPlay and Android Auto, as well as natural-language voice recognition.
• Safety: Standard driver-assistance features include automatic emergency braking, forward-collision warning, blind spot monitors, safe-exit assist, lane-keep assist, parking assist, and Pre-Safe, which cinches seatbelts, closes windows, and generally preps for a collision if an imminent one is detected.
• Starting price: Pricing starts at $113,850 for the SL 43 (all prices include a mandatory $1,350 destination charge) and the SL 55 and SL 63 start at $143,600 and $189,200, respectively.

If you're buying used today, the 2023 model year offers the best mix of value and availability. If you want the latest tech and features, it may be worth waiting for 2028 inventory to mature.
