Mercedes-Benz W210 (E-Class): A Comprehensive Guide

The Mercedes-Benz W210, the second generation of the E-Class, marked a significant departure from its predecessor, the W124. Produced from 1995 to 2002 (sedan) and 1996 to 2003 (wagon), it represented a move towards a more modern, technologically advanced, and arguably more stylish design. This guide provides a detailed overview of the W210, covering its history, generations, reliability, driving experience, and buying advice.

1. Introduction: History and Class

The W210 E-Class was a mid-size luxury car positioned to compete with the BMW 5 Series, Audi A6, and other executive sedans. It was available in both sedan (W210) and wagon (S210) body styles. Its distinctive design, featuring the now-iconic "four-eyed" headlight design, was initially controversial but ultimately proved successful, ushering in a new era for Mercedes-Benz styling. It offered a wide range of engines, from fuel-efficient four-cylinders to powerful V8s, catering to diverse customer needs.

2. Generations and Key Changes

First Generation (1995-1999)

Design Introduction: The most significant change was the adoption of the "four-eyed" headlight design, a departure from the traditional rectangular lights.
Engine Options: A wide range of engines were offered, including inline-four, inline-six, and V6 gasoline engines, as well as inline-four and inline-five diesel engines. V8 engines were introduced later.
Technology: Available features included climate control, power seats, cruise control, and optional electronically controlled air suspension (Airmatic).
Transmissions: Available with both manual and automatic transmissions.

Second Generation (1999-2002/2003)

Facelift (1999): The W210 received a mid-cycle facelift with minor exterior and interior updates. These included updated bumpers, side skirts, and taillights. The interior received improved materials and updated controls.
Engine Upgrades: Some engines were upgraded or replaced during the facelift. A new range of V6 engines was introduced, offering improved performance and fuel efficiency.
Enhanced Features: Additional features became available, such as rain-sensing wipers, upgraded audio systems, and enhanced safety features like Brake Assist.
Trim Levels: Trim levels typically included Classic, Elegance, and Avantgarde, each with its own distinct styling and equipment levels. AMG versions (E55 AMG) offered high-performance options.

3. Reliability & Common Issues

The W210, while offering a luxurious experience, is known for having certain reliability issues, especially in older models. Addressing these issues proactively is crucial for a positive ownership experience. Here's a detailed breakdown:

Rust

Severity: Rust is the W210's most significant and well-documented weakness.
Location: Common rust locations include the wheel arches (especially rear), door bottoms, trunk lid, and undercarriage. Check these areas meticulously.
Causes: Poor factory rustproofing, particularly in pre-facelift models, is often cited as the primary cause. Models from certain production locations (like Mexico) might be more susceptible.
Mitigation: Thorough inspection before purchase is essential. Repairing rust can be expensive and may only delay further corrosion. Consider models that have been garaged or regularly treated with rust inhibitors.

Electronics

Severity: Electronic issues are relatively common and can be frustrating to diagnose and repair.
Issues: Problems can include faulty window regulators, malfunctioning central locking systems, failing instrument clusters (pixels fading), and issues with the climate control system.
Causes: Aging wiring, corroded connectors, and failing electronic control units (ECUs) contribute to these problems.
Mitigation: Ensure all electronic functions work correctly during the inspection. Check for warning lights on the dashboard. A diagnostic scan with a Mercedes-Benz specific scanner can help identify potential issues.

Suspension

Severity: Suspension components wear out over time, affecting ride quality and handling.
Issues: Common issues include worn ball joints, control arm bushings, and shocks/struts. The Airmatic air suspension, if equipped, is prone to failure and can be costly to repair or replace with conventional springs.
Causes: Road conditions, driving style, and age contribute to suspension wear.
Mitigation: Listen for unusual noises (clunking, squeaking) during test drives. Inspect the suspension components for visible wear or damage. Consider the cost of Airmatic repairs before purchasing a model with air suspension.

Engine

Severity: Engine reliability varies depending on the specific engine. Inline-six engines are generally considered more reliable than early V6 engines. V8 engines can be reliable but require proper maintenance. Diesel engines are generally durable but can suffer from injector issues and fuel pump problems.
Issues: Potential issues include oil leaks (especially around the valve covers and head gasket), coolant leaks, and problems with the mass airflow sensor (MAF). Diesel engines can experience issues with the fuel injection system and turbocharger.
Causes: Age, mileage, and lack of proper maintenance contribute to engine problems.
Mitigation: Check for oil leaks and coolant leaks. Listen for unusual engine noises. Ensure the engine starts easily and runs smoothly. A compression test can reveal potential issues. Review the service history for evidence of regular maintenance.

Transmission

Severity: Automatic transmissions can be prone to issues if not properly maintained.
Issues: Common issues include rough shifting, slipping, and delayed engagement. Manual transmissions are generally more reliable.
Causes: Lack of fluid changes, worn clutches (in manual transmissions), and failing solenoids in automatic transmissions contribute to transmission problems.
Mitigation: Ensure the transmission shifts smoothly and without hesitation. Check the transmission fluid level and condition. Review the service history for evidence of regular transmission fluid changes.

4. Driving Experience

The W210 offers a comfortable and refined driving experience, typical of a Mercedes-Benz. However, the driving dynamics vary depending on the engine and suspension setup.

Pros:

Comfort: Excellent ride quality, especially on models with the standard suspension. The seats are comfortable and supportive, making it suitable for long journeys.
Refinement: Quiet cabin and smooth engine operation (particularly in V6 and V8 models).
Features: A good range of features available, including climate control, power seats, and a premium sound system.
Performance: Engine choices ranging from economical to powerful. The E55 AMG offers exhilarating performance.

Cons:

Handling: The handling can feel a bit soft and disconnected compared to more sporty rivals. Airmatic suspension can improve handling but is prone to failure.
Reliability: As discussed, reliability can be a concern, especially with rust and electronic issues.
Running Costs: Maintenance and repair costs can be relatively high, especially for complex systems like the Airmatic suspension.

5. Buying Advice

Purchasing a W210 E-Class can be a rewarding experience if you do your research and choose carefully. Here's some advice:

Years to Look For:

Facelift Models (1999-2002/2003): These models generally have better rustproofing and updated features.
Well-Maintained Examples: Look for cars with a complete service history and evidence of regular maintenance.

Years to Avoid (Potentially):

Early Production Years (1995-1997): These models are more prone to rust and may have fewer features.
Models with Airmatic Suspension (Unless in Perfect Condition): The Airmatic suspension can be a costly headache if not properly maintained. Be prepared for potential repair bills.

Key Inspection Points:

Rust: Thoroughly inspect the entire car for rust, paying particular attention to the areas mentioned above.
Electronics: Test all electronic functions, including the windows, central locking, climate control, and instrument cluster.
Engine and Transmission: Check for oil leaks, coolant leaks, and unusual engine noises. Ensure the transmission shifts smoothly.
Suspension: Listen for unusual noises and inspect the suspension components for wear or damage.
Service History: Review the service history for evidence of regular maintenance.
Pre-Purchase Inspection: Consider having a qualified mechanic perform a pre-purchase inspection to identify any potential issues.

By carefully considering these factors, you can increase your chances of finding a reliable and enjoyable W210 E-Class that provides a taste of classic Mercedes-Benz luxury.
