Part of the old Studebaker plant was used to produce Humvees for the Army. I remember going through town and seeing a dozen or so enroute to somewhere.
But the leadership of the city just couldn't stand the owner and his old buildings standing in the way of their plans to remake the area. The city harassed him with constant inspections and code violations for codes that didn't exist when the Studebaker existed and of course would never have been cited for because Studebaker was the bread and butter of the city.
It got so bad with the fines and demands for upgrades that the poor guy couldn't deal with it any more and was forced to shut down and sell off what he could. A lot of parts ended up being sold for scrap because it was impossible to save it all, though one man did pull many semi loads out before the end.
So yeah screw South Bend.
