6 Series
The BMW 6 Series builds on BMW's sporty heritage with aggressive lines and an incredible motor to back the design up. Available in coupe and convertible trims with a standard 4.8 liter engine producing 360 horsepower and 360 lb-ft of torque, the 6-series is a popular choice that exceeds expectations. |

Knocking
This problem honestly made me second guess everything. The BMW regional mechanic even came in, looked at the car and said it was "normal." I can say after driving the car for another 40K miles that the sound is still there - not much worse, not better in any way at all and the engine still seems sound. I get the occasional increased emissions warning that everyone seems to get (ethanol free gas seems to usually cure it), and have had a couple small things done, but the knocking sound is obvious as ever w/no adverse effect (that I can tell) yet to the engine...
