Positioning:
The Mercedes-Benz 190 E (W201) was a pivotal model for Mercedes-Benz, designed to capture a broader market segment while retaining the brand's reputation for quality, safety, and engineering. It was positioned as a 'compact executive' sedan, competing with offerings from BMW (3 Series) and Audi (80/90).
Competitors:
Primary competitors included the BMW E30 3 Series, Audi 80/90 (B2/B3), and the Volvo 240/740. The 190 E was often praised for its superior ride quality, build solidity, and advanced engineering for its time, though sometimes perceived as less sporting than its BMW rival.
Distinctive Attributes:
Iconic 'Baby Benz' design by Bruno Sacco, advanced multi-link rear suspension (unique in its class at launch), robust construction, emphasis on safety, and the proven Mercedes-Benz engineering standards. The 2.3L M102 engine provided a balance of performance and efficiency for its era.

Oil Change:
Typically every 7,500 - 10,000 miles (12,000 - 16,000 km) or 12 months, whichever comes first. Consult manual for exact interval and oil type.
Air Filter:
Inspect every 10,000-15,000 miles (16,000-24,000 km), replace as needed or at 30,000 miles (48,000 km).
Fuel Filter:
Replace every 30,000-40,000 miles (48,000-64,000 km).
Spark Plugs:
Replace every 30,000-50,000 miles (48,000-80,000 km), depending on plug type (standard or platinum). Refer to manual for specifications.
Coolant:
Flush and replace coolant every 2-3 years or 30,000-50,000 miles (48,000-80,000 km).
Engine Oil:
Refer to manual for API service classification and viscosity grade (e.g., SAE 10W-40, 15W-40, or 5W-40 synthetic). Mercedes-Benz approved oils often carry specific MB approvals.
Brake Fluid:
DOT 4 brake fluid is typically recommended. Ensure fluid is changed and system bled periodically (e.g., every 2 years).
Power Steering Fluid:
Refer to manual for specific hydraulic fluid type (often a type A or Dexron-compatible fluid, or a specific MB fluid).
Transmission Fluid:
Manual: GL-4 or GL-5 gear oil, 75W-90 or 80W-90. Automatic: Refer to manual for specific MB specification (e.g., ATF 3403-M115 or Dexron III compatible).

Areas prone to rust include wheel arches, rocker panels, door bottoms, and trunk floor. Regular inspection and rustproofing are recommended.
Legacy:
Mercedes-Benz, founded in 1926, has a long-standing reputation for luxury, engineering excellence, and pioneering automotive technology, particularly in safety and durability.
W201 Development:
Developed under the codename 'Projekt 1.0' (Project 1.0) and launched in 1982, the W201 (190/190E) was a significant departure for Mercedes-Benz, aiming to create a smaller, more affordable, yet still premium vehicle. The 2.3L engine was part of the initial offering, with subsequent updates and performance variants (e.g., 190E 2.3-16, 190E 2.5-16 Evolution) emerging later.
Production Years:
1982-1993
Manufacturing Locations:
Primary production in Bremen, Germany. Some assembly may have occurred in other Mercedes-Benz facilities globally.
