- Reliability (2)The M156 engine is prone to expensive head bolt failures and camshaft wear, and the complex Airmatic suspension system is a frequent point of failure as the vehicle ages.
- Maintenance (2)Owning an AMG requires a significant budget; specialized parts like oversized brake rotors and performance tires, along with the requirement for high-quality synthetic oils, lead to high running costs.
- Technology (3)While it featured advanced tech for 2008 like Keyless-Go and Harman Kardon audio, the COMAND infotainment system is dated, lacks modern smartphone integration, and has a steep learning curve.
- Comfort (4)Despite its performance focus, the cabin remains quiet and the multicontour seats offer excellent support, though the AMG-tuned Airmatic suspension is noticeably firmer than the standard E-Class.
- Dynamics (5)The 6.2L naturally aspirated V8 is a masterpiece of engineering, providing 507 horsepower and a visceral soundtrack that makes this one of the best-performing luxury sedans of its era.
