Why might have somebody done this?

Black stuff is a tar, butyl rubber, or similar material meant to dampen the resonant frequencies/reduce vibrations. Pretty standard stuff to apply to large panels. Not sure what was done originally in these areas, but it ain't hurtin' being there.

Can you back this claim somehow? Why would the parcel shelf bottom have matching holes as well, then...

Nascar uses the foam as a crumple zone,energy absorbing area. 

I do think they drank all the beer and thought it was a good idea to install the cooler in the side of the 02.

I think it's amazing how a lonely piece of tarred material can dampen sound vibration, but it does.  Thunk vs woow.  Like many 02s, my inner door material had fallen off years ago to sit in the bottom of the doors. A very hollow sound when closing the doors.  Once I applied a couple of squares (12" x 24") of "Fatmat" style of material, the doors close with a new-car thunk. All the difference in the world.

That is much easier to remove than spray foam. (someone posted photos of that having been done to their car).

 

I often thank the PO of my car for all that they did not do to it... whoever she was.

The sound deadener on the outside quarter panel looks redone. Mine was much cleaner looking and smaller, I think. 

You've got your answer on the foam. Dumb shit applied.

 

I'm not too keen on all that seam sealer at the top of your trunk wall. Looks rather, err, non factory. Or those holes either. Maybe it had some sort of roll bar?

Thanks. Good info.

 

I also think it looks weird and definitely not factory. However, I'm certain that there has been no cage in the car. 

 

The sound insulation on the side looks clean enough to belive it might be factory I'd say. It would be very hard to remove it as clean as it looks plus considering this car has only had two previous owners of which one put the white stuff there would lead me to belive that this was not tampered with.

 

The holes also look fine. If I look here: https://www.ebay-kleinanzeigen.de/s-anzeige/bmw-alpina-1600-2-rohkarosse-karosse/1225055213-223-1220 the holes are matching to what I have. I think the hole on the wheel well corner on the right is for the wires that go to the trunk floor, and it seems to me that factory made the same hole for the other side as well, as it looks identical. Maybe RHD cars have that going other way? (probably not)

 

On the parcel shelf there has been some speakers for sure. I think it's quite hard already to find example that has never had speaker holes cut there. There were also some cut wires on both side floor under the back seat to confirm the fact. Plus the fact that the parcel shelf that came with my car is for sure not factory.

 

Also notice the black stuff around the antenna cable hole.

The shape of the resonant- damping pad changed over the years, and some stuck

better than others. It's not uncommon to find it rolled up in the bottom of the panel

on a dark- colored roundie that came from a hot climate.

 

As to the applied black goop, that actually looks like an intelligent attempt to seal up

the trunk area.  

 

The other?  I maintain: "PO"!!!

Could you please send a pic of how the reinforcement (the one with the round hole)  between the quarter panel and the inner wheel house is welded ? Thanks!!

[theNomad]

The holes to the trunk are filled with a chunk of soft foam to block vapors or sound apparently. I redid all the sound deadening but you can see the foam.

The black "goo" you see on your pic is indeed some soft tar like moldable weather stripping "putty" of some sort. I have a bit of it from the PO and it seals up the holes nicely at the gas line to passthrough and the similar hole on the opposite side.
