Overview
The Mercedes-Benz CLS-Class is a large luxury car with coupe-like styling. It was last redesigned for the 2019 model year and gets updated tech features for 2021. It competes with cars like the Audi A7 and Genesis G90.
The CLS-Class is a big four-door car, though it’s graceful and elegant thanks to its low stance, sleek roofline, and blacked-out B-pillar for the the-oh-so-popular coupe-like profile. The wide grille and angled headlights make the front end look a little more sporty than you might expect based on the side view, and because it’s a Mercedes, the various wheel designs are gorgeous.
There are two CLS models, the CLS 450 and the AMG CLS 53, both carrying over unchanged this year. The CLS 450 features an inline-six engine rated for 362 horsepower and 369 pound-feet of torque, a nine-speed automatic transmission, and a mild-hybrid electrical system. Rear-wheel drive (RWD) is standard and Mercedes’ 4MATIC all-wheel drive (AWD) system is available. The AMG model is tuned for 429 hp and 384 lb-ft, and also features a (performance-enhanced) nine-speed transmission and AWD. With the base CLS, you’ll get 24 mpg city, 31 highway, and 26 combined, or 23/26/30 with AWD. The AMG CLS 53 is rated for 21/27/23.
The CLS seats five on leather upholstery and includes features like keyless entry, push-button start, and 64-color ambient lighting. The AMG model adds upgraded upholstery and a sport steering wheel. Options across the lineup include heated and cooled seats, massaging seats, and three-zone automatic climate control.
For 2021, the CLS gets an updated infotainment system in the form of the Mercedes-Benz User Experience (MBUX) system. A 12.3-inch display pairs with a new 12.3-inch digital gauge cluster for all functions, and Apple CarPlay and Android Auto are also included. The adaptive cruise control system now incorporates live traffic data—another nice touch. Buyers have the choice of two Burmester audio systems.
Standard safety features include blind-spot monitoring, forward-collision warning, automatic emergency braking, and driver-attention monitoring. For 2021, the automatic emergency braking system responds to oncoming traffic.
The lovely CLS-Class remains an enticing choice, and the updated tech features help it stay competitive.

Is the 2021 Mercedes-Benz CLS a good car?
The 2021 Mercedes-Benz CLS sits in a moderate market position, which makes it a reasonable option if you want a luxury sedan with some shopping flexibility. The current market also shows 36.4% of listings as good or great deals, which gives you a useful starting point when comparing individual cars.
What should I look for when buying a used 2021 Mercedes-Benz CLS?
Accident-free inventory is solid at 77.7% — always verify the vehicle history report.
You should prioritize a history report first, then focus your inspection on condition, maintenance records, and any signs of prior damage or inconsistent repairs. Because the clean-inventory share is strong but not universal, it pays to compare examples carefully and avoid paying a premium for a car with incomplete documentation or visible wear.
Is now a good time to buy a used 2021 Mercedes-Benz CLS?
This looks like a moderate, selective buyer’s market, so you have room to shop carefully rather than rush into the first example you see.
- Deal availability: 36.4% of listings are priced as good or great deals.
- Inventory: There are 121 listings available.
- Clean inventory: 77.7% of listings are accident-free.
That mix suggests you can find value if you compare condition and pricing closely. If you want the best odds of landing a strong example, focus on well-documented cars and use the deal share as a filter rather than a guarantee.
Should I buy a 2021 Mercedes-Benz CLS or consider a different year?
If you're weighing the 2021 against nearby model years, here's how to think about it:
Choose the 2021 if:
- 36.4% of listings are priced as good or great deals.
- Accident-free inventory is solid at 77.7% — always verify the vehicle history report.
The bottom line: The 2021 is the better path if you want a current-year option with a decent share of attractive listings and a healthy pool of accident-free cars. If you’re especially price-sensitive, it can still make sense to compare nearby years and choose the one with the best combination of condition, history, and asking price.
