The E400 4MATIC as a Used Car: A Comprehensive Buying Guide
As the Mercedes E400 4MATIC is now primarily available on the pre-owned market, it represents a fantastic value proposition. But buying a used German luxury car requires due diligence.
Why Consider a Used E400 4MATIC?
The primary reason is the E400 4MATIC depreciation curve. A model that once cost upwards of $65,000-$75,000 can often be found for less than half that price after just a few years. This means you can get a tremendous amount of car—performance, luxury, and technology—for your money. The answer to “Is E400 4MATIC a good used car?” is a resounding yes, provided you find a well-maintained example.
What to Look For When Buying Used
When you’re inspecting a potential purchase, insist on a complete service history. These are complex machines, and consistent, documented maintenance is non-negotiable. Pay close attention to tire wear, brake life, and any warning lights on the dash. A pre-purchase inspection (PPI) by a certified Mercedes-Benz technician is one of the best investments you can make.
E400 4MATIC Reliability and Common Problems
Generally, the E400 4MATIC reliability is considered good for its class. The M276 V6 engine is a proven workhorse. However, like any complex luxury vehicle, there are potential issues to be aware of. Some owners have reported minor electronic gremlins with the infotainment system or sensors. Oil leaks around the camshaft magnets or turbocharger coolant lines can occur as the vehicle ages. It’s crucial to budget for higher-than-average maintenance and potential repair costs.
E400 4MATIC Depreciation Curve
While its initial depreciation is steep (which benefits you as a used buyer), the value tends to stabilize after the 4-5 year mark. Well-maintained examples hold their value reasonably well within the used luxury market.

Financing and Insurance Considerations
Remember to factor in the total cost of ownership. Insurance premiums for a powerful luxury car will be higher than for a standard vehicle. Secure financing pre-approval before you start shopping to know your budget.
E400 4MATIC vs E450: Understanding the Evolution
Around the 2019/2020 model years, Mercedes-Benz replaced the E400 with the E450. So, what’s the difference in the E400 4MATIC vs E450 matchup?
Key Differences in Powertrain
The biggest change was under the hood. The E450 swapped the E400 V6 for a new 3.0-liter inline-six engine, often paired with a mild-hybrid system called EQ Boost. This new engine produced more power (around 362 hp) and was even smoother and more efficient than the V6 it replaced.
Performance and Driving Feel Comparison
The E450 feels slightly more responsive from a standstill, thanks to the electric assist from the EQ Boost system. It’s a subtle but noticeable improvement. However, the E400 V6 has a character of its own that many enthusiasts still love. The performance difference is not night and day; both are exceptionally quick and refined.
Which One is Right for You?
If your budget allows and you want the latest technology and a slightly more efficient and powerful engine, the E450 is a fantastic choice. However, if you’re looking for maximum value, a well-maintained Mercedes E400 4MATIC offers 95% of the experience for a significantly lower price on the used market.
Ownership Experience: Maintenance, Upgrades, and Living with an E400 4MATIC
Owning a Mercedes E400 4MATIC is a rewarding experience, but it requires commitment.

E400 4MATIC Maintenance Schedule
Following the manufacturer recommended service intervals is critical. This typically includes “Service A” and “Service B” appointments, which alternate every 10,000 miles or once a year. These services involve more than just an oil change; they include comprehensive inspections of the vehicle key systems.
Best Tires for E400 4MATIC
Tires are the single most important component for safety and performance. Don’t skimp here. High-quality grand touring all-season tires from brands like Michelin or Continental are excellent choices for balancing performance, comfort, and longevity.
E400 4MATIC Aftermarket Upgrades
While many owners prefer to keep their cars stock, a simple ECU tune can safely unlock significant horsepower and torque from the biturbo V6. Aesthetic modifications like wheels or subtle spoilers are also popular ways to personalize the car.
