Lee Iacocca had written about it in his first book. The dealers wanted more K cars and Omni/ Horizon /tc4Turismo/ Charger models, but Chrysler had a huge glut of cars like Codobra, Mirada, S.t Regis and other such automotive misfits. He said to the dealers, "We can't unmake them, so you have to sell them" Chrysler then came up with a rebate program and that annoying nationwide radio ad with the frogs saying, "rebate rebate" instead of ribbit ribbit.
