the claims it rests on
“Average vehicle age in the U.S. increased 11.3% from 11.5 years in 2015 to 12.8 years in 2025”
“Total U.S. registered vehicles increased 12.3% from 2015 to 2025 to 289 million”
“Out-of-warranty older vehicles generate strong demand for automotive aftermarket products as they go through more routine maintenance cycles and have more frequent mechanical failures”
“Average ticket values continue to be positively impacted by the increasing complexity and cost of replacement parts necessary to maintain better-engineered and more technically advanced vehicles”
what it was checked against
fleet size growth data
“As reported by the Auto Care Association, the total number of U.S. registered vehicles increased 12.3% from 2015 to 2025, bringing the number of light vehicles on the road to 289 million by the end of 2025.”
aging vehicle fleet statistics
“From 2015 to 2025, U.S. vehicle scrappage rates have remained relatively stable, ranging from 4.1% to 5.6% annually. As a result, over the past decade, the average age of the U.S. vehicle population has increased 11.3%, from 11.5 years in 2015 to 12.8 years in 2025.”
demand driver acknowledgment
“The total number of vehicles on the road and the average age of the vehicle population heavily influence the demand for products sold within the automotive aftermarket industry.”
