LAKE SUCCESS, N.Y. -- DealerTrack Holdings Inc., a provider of on-demand software and data solutions for the U.S. automotive retail industry, today announced that John Blair, the long-time CEO of Automotive Lease Guide (ALG), will be leaving the company to pursue new business endeavors. Blair was with ALG for 12 years, serving as its CEO for 10 years.

During Blair's tenure, ALG grew from a residual value guidebook company to an analytical bellwether and consulting mainstay for the automotive industry. ALG was acquired in 2005 by DealerTrack, and, with Blair's guidance, has greatly expanded its offerings and its reach in the market.

"John's leadership and vision will have a lasting effect on the long-term growth of ALG," said Mark F. O'Neil, chairman and chief executive officer of DealerTrack. "ALG has become highly influential within the automotive industry, and we thank John for consistently guiding this business forward."

Going forward, Raj Sundaram, senior vice president, solutions and services group at DealerTrack and former president of ALG, will be responsible for management of ALG. James Clark, a long-time ALG veteran and most recently the managing director of the editorial department, will assume the role of general manager. Clark will serve as senior executive in Santa Barbara, ALG's headquarters.

"It's been an honor to be at the helm of ALG for the past 10 years and I feel fortunate to have had this opportunity," said Blair. "As a DealerTrack company, ALG is well positioned to continue to break new ground in automotive forecasting."
