Friend is getting an M Coupe...

[Dinan55]

A friend of mine is most likely going to buy an M Coupe soon, this is the only thing that's worrying him: http://bimmer.roadfly.org/bmw/forums/z3-coupe/4788649-1.html

We know what it is so there's no need for an explanation; we just want to know why it happens, how it happens, and how we can stop and/or check for it. The car he plans to buy is a 1999 and has 20,340 miles on it. Anyone know anything?

Perhaps an aftermarket sub-woofer? I HIGHLY doubt a BMW would end up hurting itself, no matter what the mileage. In fact, I'm willing to bet it was due to some kind of aftermarket sub-woofer setup. In any case, does this crack affect the car's performance or its operation in any way??

In the first photo there are pieces of plastic lying about. Something broke or was broken in the car. I suspect human error. I have about 12 friends who all own M Coupes and they have zero problems and no cracks.

My friend and my neighbor both own M coupes. While they've had their problems, they've had nothing like that. The problems they've told me about are either common among BMWs or just from a lemon sold by a crappy dealer.

It's a not-so-common thing on some Z3's, M Coupes, whatever. Something about the underbody cracking and the entire differential ripping out, the case that I've posted above is the worst case I've seen yet. It's just kind of a scary thing to think of, I wouldn't be too happy if I was driving down the highway and all of a sudden my wheels passed me.
