About the Mercedes-Benz 320
The Mercedes-Benz 320 designation has been applied to multiple model lines, most commonly the E-Class (E320), C-Class (C320), and M-Class (ML320). The E320 and C320 were available as saloons, estates, and coupés, powered by either 3.0-litre V6 diesel engines or 3.2-litre V6 petrol units. The ML320 represented Mercedes' luxury SUV offering with similar powertrain options.
Production spanned from the late 1990s through to the early 2010s, with the CDI diesel variants proving particularly popular in the UK market. Standard equipment typically included leather upholstery, climate control, cruise control, and advanced safety systems. Later models featured improved infotainment systems and driver assistance technologies.
What Affects the Price
Age and mileage are primary price determinants, with post-2005 models commanding significant premiums. The diesel CDI variants typically hold their value better than petrol equivalents due to superior fuel economy and longevity. Service history is critical—cars with full Mercedes-Benz dealer records fetch considerably more than those with incomplete documentation.
Model variant significantly impacts pricing, with AMG-trimmed Sport models and estate versions often more desirable. Condition of the interior leather, paintwork quality, and absence of common issues like suspension wear or electronics faults all affect valuations. Specification levels matter, with cars featuring panoramic roofs, navigation, and premium audio systems commanding higher prices.
Buying Tips
Insist on comprehensive service history, particularly evidence of regular oil changes which are crucial for engine longevity. Inspect for rust around wheel arches and sills, especially on pre-2007 models. Check all electrical systems thoroughly, including seat adjustments, windows, and climate control, as faults can be expensive to rectify.
Listen for any unusual noises from the suspension, particularly the airmatic system on higher-spec models, which can be costly to repair. Diesel models should start cleanly without excessive smoke. Consider an independent pre-purchase inspection from a Mercedes specialist. Budget for premium fuel, potentially expensive servicing, and higher insurance costs compared to mainstream brands.
