One of the first cases of "badge engineering" began in 1917 with Texan automobiles assembled in Fort Worth, Texas, that made use of Elcar bodies made in Elkhart, Indiana. However, the transformation of the Ajax was "probably the industry's first example of one car becoming another.". Nash even made the kits available at no charge to consumers who bought Ajax cars, but did not want to own an orphaned make automobile, to protect the investment they had made in a Nash Motors product. Because of this, few unmodified original Ajax cars have survived.
