Mercedes introduces C-Class Estate

The C-Class Estate is not only an affirmation of the popularity of the Benz wagon, a popularity that transcends decades as well as engine swaps, but also a commitment to Bremen -- a facility that already builds the C-Class, along with the E-Class, SL, SLK and GLK. The C-Class Estate makes extensive use of aluminum construction -- up to 50 percent of its body is made of the stuff.
