Resurrecting dead automotive zombie brands is a fine exercise in making a small fortune by starting with a large fortune. Mercedes plowed a lot of money into bringing back Maybach in 2002 to only pull the plug a decade later. Even in the rare example where it does work it's rarely worth the effort. Longtime VW chairman Ferdinand Piech once said that if he know how much of an effort it would take to resurrect Audi he would of started with a new brand from scratch. Ford and Toyota took two different approaches to break into the luxury car business in 1990, Ford bought Jaguar (with the idea to reinvigorate the brand) and Toyota launched the Lexus brand. Needless to say one approach worked very well and the other failed.
