The former AMC HQ Building is abandoned and and has fallen into ruin.

I was surprised to read that American Motors called the Plymouth Road Office Center in Detroit their headquarters even after American Center was constructed in Southfield in the mid 1970's. Is this correct? I thought American Center served as the HQ for AMC from the time it was built.

In 1954, when Hudson and Nash merged, PROC became AMC's headquarters, until 1987, when AMC was purchased by Chrysler. At that point, PROC became the central engineering location for all corporate trucks and SUVs, a position it held until the building was cleared.

American Center - AMC's corporate headquarters in Southfield, Michigan is still standing,[71] still open, and still called "American Center". The original "American Center" signage at the top of the building remained until 2005, although the AMC logo has been removed.
