Disappointed 
2011 BMW M3 Sedan 4dr Sedan (4.0L 8cyl 6M)
Reliability Issues, disappointed
 I have owned this car for about 4 months.  I was extremely excited about he purchase and initially loved the car.  I drove as prescribed during the break-in period and never drove it like a M3 should be.  After the break-in period, I only put 300 miles on the car (for a total of 1500 miles) before the car started exhibiting problems.  The most recent of which occurred this week with loss of power, slow acceleration, etc.  Feels like I am driving a Camry.  Took it in for service and they cant seem to be able to find the issue.  If they cant resolve the issues, I think I may have bought a lemon.  Extremely disappointed in BMW and the car at the moment.
