GM's money-back guarantee

GM will begin to run ads for its new "May the Best Car Win" program. Buyers can take a new GM car off the lot and drive it for up to 60 days. If they don't like it, they can return the car without penalty between the 31st and 60th day. The offer expires on November 1.

The introduction to the program will include TV ads starring new GM chairman Ed Whitacre, who is an odd selection. Whitacre is a former phone company executive with no experience in the car industry. He is also a 67-year-old pitchman for a company that is trying to appeal to younger buyers. In short, he is the wrong choice.
