Toyota's US unit has officially marked the opening of the once-mothballed Toyota Motor Manufacturing, Mississippi (TMMMS) plant. The $800m plant outside Tupelo - built in 2007-2009 and originally intended to build the Highlander [Kluger] SUV and then the Prius - has ended up assembling the Corolla after the joint venture plant with GM in Fremont, California, that made that model was closed in 2010. Toyota also builds North American Corollas in Canada.
