NASCAR phenom Jeff Gordon has notched 58 victories and nearly $47 million in winnings without a major crack-up—until now. On March 15 his wife, Brooke, 31, announced the wheels had come off their marriage after seven years.

In filing for divorce in Florida's Palm Beach County, Brooke described her marriage as "irretrievably broken" by Jeff's unspecified "marital misconduct." (So far, he has not addressed the charge.) Racing's golden couple, the Gordons have no children but will need to sort through a bundle of assets: Brooke is seeking sole use of their 23,095-sq.-ft., $9 million home in Florida's Highland Beach, as well as alimony payments, the Porsche and Mercedes and use of their Falcon 200 airplane. Brooke also wants Jeff, 30, to keep paying for their housekeepers and chef.

Now staying with a friend, Jeff met Brooke Sealey in Daytona International Speedway's victory lane after a qualifying win in 1993; she was the stunning model who handed the handsome rookie his trophy. They were married in 1994 and did "everything together," Jeff told PEOPLE in 1997. "We have a great life."

But eyebrows raised this month when for the first time Brooke did not attend one of Jeff's races. Brooke "tried to preserve the marriage in every way possible," her attorney Jeffrey D. Fisher said in a statement. But it was not to be. Clearly, things had changed dramatically from the time that Jeff, in 1997, said, "Sometimes [women] tell Brooke how fortunate she is. And I'll say, 'No, I'm the fortunate one.' "
