"After retirement, Dykstra moved to California and started a profitable luxury car wash that he called The Taj Mahal. He expanded the business throughout Southern California and in 2007 sold it to investors, according to bankruptcy filings. As a self-taught financial analyst, Dykstra proclaimed himself a financial guru and began writing a stock-picking website column. His prominence soared as a sports celebrity, entrepreneur and popular guest on numerous financial news broadcasts. In 2008, Dykstra began publishing the Players Club, a glossy financial advice magazine exclusively for pro athletes to help them with wealth management and investment banking. But Dykstra seemed to lose control of his extravagant jet-setting lifestyle during the housing bust. His purchase of the palatial Gretzky estate in 2007 for $14 million occurred a few months before the mortgage market collapse."
