# 2005-2010 BMW M6 Coupe The E63-generation BMW M6 pairs aggressive styling with a naturally aspirated 5.0L V10 producing 500 horsepower—derived from BMW's Formula 1 program. This grand tourer blends supercar performance with daily usability, hitting 60 mph in 4.1 seconds. Reviewers praise its intoxicating V10 soundtrack and explosive acceleration, though criticize its hefty 4,000-pound curb weight and complicated SMG transmission (7-speed manual is rare but preferred). The iDrive system feels dated today. **Infamous for:** Expensive maintenance, particularly the notorious throttle actuators ($3,000+ repair), rod bearing failures, and SMG pump issues. **Best for:** Enthusiasts seeking V10 thrills on a depreciated budget who can afford $3,000-5,000 annual maintenance. Ideal as a weekend GT car rather than primary transportation. Values are rising for well-maintained examples, especially manual-equipped cars.
The E63 M6's high-revving V10 requires expensive throttle actuator replacements ($2,000-3,000), and rod bearings need preventive service every 60-80k miles to avoid catastrophic failure. SMG transmission pumps fail frequently ($2,500). Insurance rates are high due to performance classification. Expect $3,000-5,000 annual maintenance beyond typical luxury cars. Parts and specialist labor are premium-priced.
