2007 BMW M6
Overview
The 2007 BMW M6, a high-performance grand tourer, is known for its exhilarating driving dynamics and powerful V10 engine. However, like many complex performance vehicles of its era, it presents a mixed bag in terms of long-term reliability. Owners often praise its thrilling acceleration and handling, but potential buyers should be aware of specific areas that have historically shown a propensity for issues. These tend to be concentrated in the powertrain, particularly the V10 engine and its associated systems, as well as certain electronic components. Regular and meticulous maintenance is paramount for mitigating these potential problems and ensuring the M6 remains a rewarding, albeit demanding, ownership experience.

Summary Verdict
The 2007 BMW M6 is a performance icon that demands a premium for its upkeep. While the manual transmission variant is generally more reliable, the SMG III can present costly issues related to its hydraulic system. The V10 engine, while potent, is prone to expensive problems like rod bearing wear and throttle actuator failures, requiring vigilant maintenance and potentially significant repair budgets. Electrical gremlins and suspension component failures, particularly with the advanced Adaptive Drive system, are also points of concern. Prospective owners should budget for higher-than-average maintenance and repair costs, and prioritize vehicles with a documented service history, especially concerning the engine and transmission.
