How much does the 2020 Mercedes-Benz E-Class cost?

Prices have softened 7.50% compared to this time last year, making it a favorable time to shop this model year.

There are 1,016 listings available, which suggests solid inventory for you to compare across body styles and trims.

If you find a listing below $29,935.01, that's toward the low end of the year-round range and worth acting on quickly.

Is the 2020 Mercedes-Benz E-Class a good car?

Yes — the 2020 Mercedes-Benz E-Class earns a 5/5 user rating and an 8/10 expert rating. The standout strength is Safety at 10/10.

It comes across as a premium car that feels special, with multiple body styles, a stylish design, and impressive technology. For you, that means broad appeal if you want a luxury car that can be tailored to different tastes and uses.

The trade-offs are clear: the base engine is described as underwhelming, and the technology can be difficult to use. Even so, the market still shows 33.2% good or great deals, which gives you some room to shop selectively.

Is the 2020 Mercedes-Benz E-Class reliable?

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

The E-Class is described as a rock-solid, impeccably built car, and the expert notes reinforce that impression with language about its strong build quality and refined demeanor. Its performance notes also point to a car that feels composed and well sorted in everyday driving.

The ownership risk for you is mainly financial rather than mechanical: these cars depreciate quickly, so buying used can help you avoid the steepest early value loss.

What should I look for when buying a used 2020 Mercedes-Benz E-Class?

At 67.2% accident-free, a meaningful share of listings has prior incidents — history verification is especially important.

You should start with a vehicle history report and then prioritize a pre-purchase inspection, especially if you are comparing cars with similar prices. Focus on condition, equipment, and whether the car has the features you actually want, since this model can vary a lot by body style and option content.

Key things to evaluate:

• Trim level: The base E-Class sedan is described as well equipped, but it still uses leatherette and standard seats, while richer versions add more lavish materials and features.
• Powertrain: The 2.0-liter turbocharged four-cylinder is improved, but it is still described as underwhelming for a heavy car; the 3.0-liter twin-turbo V6 is the stronger everyday choice.
• Safety package: The Driver Assistance Package adds the semi-automated driving system, including steering assistance, obstacle avoidance help, lane changes, curve slowing, and broader sensing around the car. Many other driver-assist features are optional.
• Infotainment: Bluetooth, Apple CarPlay, and Android Auto are standard, and the dash can be reconfigured in multiple designs. The system is still described as difficult to use.
• Fuel efficiency: Fuel economy is EPA-estimated between 19 to 23 mpg city and 26 to 32 highway, depending on powertrain and body style.

Which 2020 Mercedes-Benz E-Class trim should I buy?

The 2020 Mercedes-Benz E-Class is offered in 4 trim levels: E350 sedan, E450 coupe, E450 4Matic wagon, E450 cabriolet.

Here's the short version:

• E350 sedan: This is the entry point, and it gives you the core E-Class experience at the lowest starting price. It suits you if you want the most accessible way into the lineup and can live with the base engine’s weaker performance.
• E450 coupe: This is the better pick if you want stronger power and a more upscale two-door feel. It adds the V6’s smoother, more effortless character over the E350.
• E450 4Matic wagon: Choose this if you want the most practical body style in the lineup with all-wheel drive and a more versatile layout.
• E450 cabriolet: This is the style-first choice if open-air driving matters most to you, but it sits at the top of the price range.

The safety package note to keep in mind is that the Driver Assistance Package contains the full semi-automated feature set, while many other driver-assist features remain optional.

Is now a good time to buy a used 2020 Mercedes-Benz E-Class?

This looks like a moderate, selective buyer’s market, so you can shop patiently but should move quickly on the right car.

• Deal availability: 33.2% of listings are priced as good or great deals.
• Inventory: There are 1,016 listings available.
• Price trend: Prices have softened 7.50% compared with last year.
• Clean inventory: 67.2% of listings are accident-free.

If you find a listing below $29,935.01, that's toward the low end of the year-round range and worth acting on quickly.

What is the 2020 Mercedes-Benz E-Class's resale value?

The current average of $30,553 sits slightly below last year's $33,031.

That decline suggests the market has already absorbed some of the model’s depreciation, which can help you if you buy used and later resell. If you choose carefully, you may be able to limit your own loss by starting from a lower purchase price than earlier buyers paid.

The strongest resale candidates are usually the cars with the right equipment, clean history, and broad appeal, especially in a model like this where body style and options can matter a lot. 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 2020 Mercedes-Benz E-Class safe?

The E-Class sedan and wagon scored a 5-star overall rating and 5 stars in frontal and side crash tests and for rollover vulnerability from the National Highway Traffic Safety Administration (NHTSA). The sedan is rated a Top Safety Pick+ by the Insurance Institute for Highway Safety (IIHS) with the highest ratings in six crash tests, headlights, and collision-avoidance systems.

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

The Driver Assistance Package adds the semi-automated driving system, including steering assistance, obstacle avoidance help, lane changes, curve slowing, and sensing around the car from multiple directions. Standard safety equipment includes forward emergency braking, a driver attention monitor, and blind-spot monitoring.

One caveat for you: the coupe and cabriolet were not tested by IIHS or NHTSA, so the strongest crash-test results apply to the sedan and wagon.

Should I buy a 2020 Mercedes-Benz E-Class or consider a different year?

If you're weighing the 2020 against nearby model years, here's how to think about it:

Choose the 2020 if:

• 33.2% of listings are priced as good or great deals.
• At 67.2% accident-free, a meaningful share of listings has prior incidents — history verification is especially important.
• Price trend: Prices have softened 7.50% compared with last year.
• Owners rate it 5/5 — a strong satisfaction signal.
• The 2020 adds a new base engine while keeping the E-Class’s stellar design, technology, and effortless demeanor.

Consider the 2021 if:

• At $35,920, the 2021 costs more than the current year's $30,553 average.
• It gets a mid-cycle update for the infotainment system, engines, and exterior styling.

The bottom line: If you want the better value, the 2020 is the smarter starting point because prices have softened and inventory is healthy. If you care more about the updated infotainment and styling, the 2021 is the cleaner upgrade, but you should expect to pay more for it.
