A growing share of the used car market is being driven by a shift in how dealerships manage their vehicle fleets, with more cars being converted into low-mileage certified used inventory through service loaner programs. Dealers are increasingly motivated to participate in these initiatives, which help boost their supply of pre-owned vehicles. The strategy allows dealerships to recoup value from cars temporarily out of service while meeting rising consumer demand for reliable, lightly used alternatives. This trend reflects broader changes in how automakers and retailers handle vehicle turnover and inventory cycles.
Much of the increase comes from incentivizing dealerships to turn more vehicles into service loaners, which later become low-mileage certified used inventory.
