Here is example A of how BMW is going to complete ****. After talking to several owners, I decided against buying an M3 and thought perhaps maybe it was isolated, but in any event, I should wait and see. I waited, and I saw, and I'm horrified.

The S54 BMW 3.2 liter 333HP I-6, found in the E46 M3 and M Roadster/Coupe
BMW E46 M3 Engine Failure Archive
This is for the E46 BMW M3 archive. It lists 56 engine failures owners of this website have had alone.
Some interesting facts: Of all the engine failures, 43% of those occured in cars that were produced in November of 2001. Of those, 85% were SMG optioned automobiles. Most of the engine failures occured at between 5,500 and 9,000 miles.
Please also note the wonderful service BMW has provided it's owners. This is what a $50,000 car from BMW buys you, everyone.
