Chrysler/Fiat CEO Sergio Marchionne is looking for ways to put the newly combined Fiat and Chrysler in Detroit, rather than Italy, where Fiat is from. Could it be the newly refurbished Chrysler House? Maybe, since the headquarters staff would be relatively small, a few dozen at most, while the Chrysler and Fiat groups would remain based in Auburn Hills, Mich., outside of Detroit, and Turin, Italy, Fiat’s historic home.
