What are common maintenance issues with the BMW M3?

I am considering purchasing a BMW M3, but I want to be aware of any potential maintenance issues before making a decision. Can anyone provide insight into common problems or issues that I should be aware of?

As an owner of a BMW M3 for over 5 years now, I can confidently say that the most common maintenance issue I have encountered is with the electronic water pump. It tends to fail around the 80,000 mile mark and can be quite costly to replace. My advice would be to proactively replace it before reaching that mileage to avoid any potential issues.

One common issue with the BMW M3 is with the engine rod bearings. I've heard of many owners having to replace them around the 50,000 mile mark. To prevent this issue, make sure to use high-quality oil and change it regularly according to BMW's recommended schedule.

I've had my BMW M3 for over 10 years now and the biggest maintenance issue I have faced is with the transmission. It can be quite expensive to replace, so my advice would be to take care of it by not accelerating too aggressively and making sure to get regular maintenance done.
