the mustang ii helped keep the ponycar alive between 1974 and 1978. general motors almost stopped building their popular chevrolet camaro and pontiac firebird; chrysler corporation stopped building the dodge challenger and plymouth barracuda during that time. general motors stopped building the camaro in 2002, but they brought back a new version in 2009. chrysler brought back a new challenger in 2008 as well; they, like today's mustang, are made to look like older models.
