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.
