According to a Reuter's news report today, GM's sales push (as previously discussed here on Marketing Genius) resulted in a 41% increase in sales for June 2005, compared to June 2004. In fact, GM led all American automakers in sales volume for the month of June. It was GM's biggest sales month since 1986. However, the report questioned whether or not the deep discounting will run the company into the red.
It was a desperation move. It appears that GM had to do something drastic that would generate some quick sales. Whether we marketing folks agree or disagree with the merits of the strategy, it looks like GM got what it wanted.
