* Based on opinions and should be considered as general guidance only.
- Reliability (2)This specific model year is plagued by the infamous M272 balance shaft gear issue, which is a catastrophic and expensive engine-out repair if not already addressed.
- Maintenance (2)Service costs are high due to specialized parts and labor; electronics can be finicky as they age, making it an expensive car to keep in top condition.
- Technology (3)For 2006, the COMAND interface and optional Harman Kardon sound system were respectable, but the navigation system and lack of modern integration now feel very dated.
- Comfort (5)The pillarless side window design provides an airy feel, complemented by high-quality interior materials, excellent sound insulation, and very supportive front seats.
- Dynamics (4)The 268-hp 3.5L V6 provides smooth, linear acceleration and the 7G-TRONIC transmission is refined, though the handling leans more toward stable cruising than sharp cornering.
