Beyond that, I've got nothing.

The aluminum subframe is unique to the M3. Aluminum is quite tricky to weld and does not make as "clean" seams as steel.

That makes sense, especially considering I couldn't find anything that looked remotely like that. I knew these cars were a lot different, I just didn't realize how much different they really are!

Despite what Atombyte says, the welds are actually pretty clean. The roll-out is contiguous and fluid save for one "pause point" in the middle. You can tell they were performed by a robot.
Thanks for the explanation! I might have also freaked if I saw that when mine comes in. I'm used to seeing cars in all kinds of bad dis-repair, with some really crappy welds holding things together, but I'm admittedly ignorant when it comes to aluminum welds.
