MOTOR TREND EDITORS SELECT CHEVY CORVETTE AS WINNER OF “EDITORS’ COOLEST CAR CHALLENGE," PRESENTED BY XM SATELLITE RADIO

Chris H. of Elk Grove, Calif., Wins $10,000 Prize for Matching Editors’ Picks

Los Angeles, Calif., December 11, 2007 – The editors of Motor Trend, part of SOURCE INTERLINK MEDIA, announced today the selection of the Chevrolet Corvette as the winner of The Editors’ Coolest Car Challenge: from Sixty-Four Cars to One, presented by XM Satellite Radio.

The Editors’ Coolest Car Challenge invited readers of leading titles Motor Trend and Automobile Magazine to match their automotive wits against the editors. Using an NCAA-style tournament bracket, readers selected from 64 XM-equipped vehicles, which were pitted against one another to try to guess which vehicle would match the editors’ choice for Coolest Car. The Corvette came out on top.

“Other rides have plenty of claim to the title of cool, but almost none of them can say they have been cool for as long as the Corvette," said Arthur St. Antoine, editor at large for Motor Trend. “It’s the original star-spangled two-seater, and it’s been turning heads for more than half a century. Race-bred suspension and road-hugging performance grace every model, and cool features abound. The Corvette silhouette is unmistakable."

Chris H. of Elk Grove, Calif., won the grand prize of $10,000 toward the purchase of the XM Coolest Car. His name was drawn at random from the group of entrants who filled out the bracket.

“We congratulate Mr. Harner on his big win and sharp automotive instincts," said Jeff Curry, vice president, automotive marketing for XM. “No matter what your definition is of what makes a car cool, XM Radio is fast becoming a critical feature of the ultimate driving experience."

The field of 64 XM-equipped vehicles featured a wide range of styles and makes, from the performance-driven Ferrari 612 to the eco-conscious Toyota Prius. In many matchups, readers had to make difficult choices between different kinds of cool, like the luxurious strength of the Infiniti QX or the nimble speed of the Lotus Elise.

Fans can see the complete results of the head-to-head matchups and more of what Motor Trend editors had to say about the winner at www.XMCoolestCar.com.

Motor Trend, Automobile Magazine and XM promoted the challenge via an integrated online and print campaign that was exclusive to the two publications.
