"Ultimately, the campaign created a paradox. Similar to Richard Nixon's "I am Not a Crook!" speech, vehemently denying something tends to paradoxically reinforce its opposite. In Oldsmobile's case, trying to say newer models were "not for your father" only aged them more. It isolated buyers who actually could afford newer models, without attracting the newer generation to take their place. This ultimately resulted in a car brand which appealed to no one, and sales figures started to reflect that. The 1980s regularly saw sales between 800,000 to 1 million units before those numbers started to drop. After 1990, Oldsmobile never again sold more than 500,000 units per year, no matter what campaigns it tried to enact to recoup losses. This can all be traced back to the late 1980s, when Oldsmobile unfortunately learned this lesson the hard way: Don't alienate your main source of income. It's a shame as well, considering the proud 100-plus year history of the company and the many important moments Oldsmobile enjoyed over that time."
