More comfortable for long journeys. Improved sound insulation compared to the W638. More sophisticated electronics, including navigation and entertainment systems. Some models offered four-wheel drive (4MATIC). Prone to injector issues, especially in the earlier CDI diesel engines. Rust can still be a problem, although generally less severe than the W638. Dual mass flywheel (DMF) failures can be costly. Electrical problems can persist. Suspension components (e.g., ball joints, bushings) can wear quickly. AdBlue system failures (on later models) can be expensive to repair. Some owners have reported issues with the automatic transmission. The V6 petrol engines can be thirsty.
W447 (2014-Present) Significantly improved safety features, including driver assistance systems. More fuel-efficient engines (especially the OM651 and OM654 diesels). More comfortable and refined interior. Excellent handling and ride quality. Available with a wide range of options and configurations. Modern infotainment systems. Strong residual values. Quieter and smoother than previous generations. Available with advanced features such as adaptive cruise control and lane keeping assist. Improved build quality compared to earlier models. More complex electronics, which can lead to higher repair costs. AdBlue system issues are still a concern. Some owners have reported problems with the automatic transmission. The cost of parts and labor can be high. Early models (2014-2016) may have some teething issues. The standard suspension can be firm. The optional air suspension (AIRMATIC) can be expensive to repair. Some owners have reported issues with the sliding door mechanism. The initial purchase price is significantly higher than older models. Potential for software glitches.

Detailed Explanations

W638 (1996-2003): The First Generation

The W638 marked Mercedes-Benz's entry into the mid-size van market. While affordable and relatively simple to maintain, its age means finding a well-preserved example is crucial. Rust is a major concern, particularly around the wheel arches, sills, and underbody. Electrical issues are also common due to aging wiring and components. While its robust diesel engines are a plus, be prepared for a less refined driving experience compared to newer models. The absence of modern safety features is another factor to consider.

Strengths of the W638:

  • Simple Mechanics: Easier and cheaper to repair, appealing to those comfortable with DIY maintenance.
  • Robust Diesel Engines: Particularly the pre-facelift models, known for their longevity.
  • Affordability: Lower purchase price makes it an attractive option for budget-conscious buyers.
  • Spacious Interior: Provides ample cargo and passenger space for its class.

Potential Weaknesses of the W638:

  • Rust Prone: Extensive rust can compromise structural integrity and lead to costly repairs.
  • Electrical Issues: Aging wiring and components can lead to various electrical malfunctions.
  • Limited Safety Features: Lacking modern safety systems, making it less safe than newer models.
  • Harsh Ride Quality: Suspension designed for load-carrying, resulting in a less comfortable ride.

W639 (2003-2014): A Step Up in Refinement

The W639 represents a significant upgrade over the W638, offering improved safety, more powerful engines, and a more modern interior. However, it's not without its faults. Injector issues are common, especially in the earlier CDI diesel engines. While rust is less prevalent than in the W638, it's still a potential problem. Dual mass flywheel (DMF) failures can be expensive to rectify. Facelift models (post-2010) saw improvements in engine efficiency and reliability, making them a more desirable choice.

Strengths of the W639:

  • Improved Safety: Enhanced safety features compared to the W638, offering better protection.
  • Modern Interior: A more contemporary interior design provides a more comfortable and appealing cabin.
  • Powerful Engines: More powerful engine options deliver improved performance and driving experience.
  • Wider Range of Configurations: Available in various body styles and configurations to suit different needs.

Potential Weaknesses of the W639:

  • Injector Issues: CDI diesel engines are prone to injector failures, leading to performance problems.
  • Rust Problems: While less severe than the W638, rust can still be a concern, especially in older models.
  • DMF Failures: Dual mass flywheel failures can result in costly repairs and downtime.
  • Electrical Problems: Electrical issues can persist, requiring troubleshooting and repairs.

W447 (2014-Present): The Modern Vito

The W447 is the most modern Vito, boasting significantly improved safety features, fuel-efficient engines, and a comfortable interior.
