The U.S. vehicle fleet population is changing, a shift that gives way to significant opportunities for certain automotive aftermarket segments according to Polk, the global automotive market intelligence firm recently acquired by IHS.

As part of its analysis, Polk reports the average age of all light vehicles on the road now stands at a record high of 11.4 years, based on review of over 247-million U.S. car and light truck registrations earlier this year.
