, as I'm sure there are hundreds, if not thousands of these cars that are driven hard, and have not had oil testing done even once. So these owners pretty much don't know there is a possibility of bearing failure, they just keep driving it.

When I got my M3 and asked about oil analysis, there was a puzzled look on sellers' face. He had the car for a long time (over 85K, second owner). Which brings me back to my point - we get all worked up because of elevated lead in oil sample, and spend $$ to replace bearings, where some folks just keep driving their cars, oblivious to the fact, and nothing happens.

So, how much of this is a reason to worry - its for you to decide.
Truthfully, almost every single platform seems to have an issue or two that the Internet goes crazy over. I feel like some are blown out of proportion while others seem to be real threats. Like anything, you have to read as much as possible and see what you feel comfortable with. Don't think of it as playing the lottery so much as self-insuring against potential loss. In the end, it's only money and time either way you decide to go. Personally, I haven't replaced my bearings and don't feel overly worked up about it. Would I like for my engine to need to be replaced? Of course not, but I'm not going to lose sleep over the E46 boogeyman either. If I took everything I read to heart on here, I would be scared to even drive my car but in reality, driving it almost every single day has been the best thing I've ever done for it. Everything seems to work much better now than when it mostly sat around, go figure.

Those bearings look similar to mine when I replaced them last year with similar wear numbers. I'm done doing sample reports and am just going to replace the current bearings once they reach 60k miles.

Pretty bad? They look like bearing with 88K miles on them. I'd say normal wear. Could probably go for another 12-15K for sure. But like you said, I wouldn't feel bad about replacing them.

I don't see where copper could be at 36ppm vs 8 avg from first post vs that pic. Lead at 49ppm vs 5avg, sure.
That pic def does not look bad. Top shells get more hammered so they have some more wear, but that's not bad condition.

Is the rod bearing replacement for all E46 M3 or just certain years? I have a 2004

The dealership doesn't do this. You'll need to do an oil change and grab some of the oil and send it to Blackstone Labs (https://www.blackstone-labs.com). It's a really easy process.
