Wow they say and I quote : "
There is very little rust on the car"
Not clear what their definition of little is but too much for me!
Technically we have seen very little rust. All best guesses without a PPI. I’ve had two very rusty e9’s and none have been rusted out below the window trim. When I see that it always gives me pause.
Seeing that they body matched the heater cover, I’m guessing the restoration glossed over some problem areas. That is why you are seeing filler swelling in funny areas.
I don’t see any rust on the roof. That is paint failing and a bad sunroof seal.
Rust at the windscreen base doesn’t translate into rust in the glovebox. The glovebox rust comes from a rusted out shock tower. The tower gets pinholes. Once this starts water after drips into the fender box and pools at the firewall (above the glovebox).
The windscreen corner is actually the outer fender, which extends towards the center of the windscreen several inches. Under that is another two layers of sheetmetal that the fender rests on.
The upper door metal rusting must be from salty condensation inside the door. Water can’t pool there, and I’ve seen it most on coastal cars (as
@teahead mentioned).
