How reliable is the BMW M3 engine?

I'm considering buying a BMW M3 and I've heard mixed opinions about the reliability of its engine. Can anyone with personal experience comment on this? Is the engine prone to frequent breakdowns or does it require a lot of expensive maintenance?

In my experience, the BMW M3 engine has been incredibly reliable. I've had my car for over 5 years and haven't had any major issues. As long as you follow the maintenance schedule and take care of it, it should last you a long time.

I've owned several BMW M3s over the years and have never had any issues with the engine. You can trust that it will perform well and last a long time, as long as you take care of it.
