Rockers, sports stars, entertainment bigs and ordinary billionaires mixed at the sold-out Barrett-Jackson Scottsdale vintage-car auction in Arizona.

Spies said former Yankee slugger Reggie Jackson bought a $650,000 Ferrari at the weeklong show that wrapped Sunday.

Barrett-Jackson’s sale was one of a number that took place during Arizona’s annual auction week for fancy cars.

Other wealthy potential buyers who were seen perusing vaunted vehicles included Alice Cooper, Gene Simmons, pro golfer Bubba Watson, Billy Baldwin, racing champs Stirling Moss and Jeff Gordon, Kareem Abdul-Jabbar and former EMI boss Charles Koppelman.

The week’s top-selling car was a red Ferrari California Spider that went for a cool $8.8 million. The week’s priciest American cars were a 1967 Corvette for $3.85 million, and a 1969 Corvette “No. 57 Rebel” for $2.86 million.
