For many years the top-selling luxury car in North America was the Cadillac. It reigned from 1950 to 1998. In 2000, Cadillac sales dropped to half of the sales in 1978.

Although Cadillac made $700 million in 2000, the company felt it must pick up sales to younger males. To put Cadillac back on top, it is necessary to understand who is buying. A survey of luxury car buyers was undertaken. The following information was gathered from random samples of recent buyers of luxury cars.
