RESTRAINT

Extended durability of modern vehicles and longer maintenance intervals reducing part turnover frequency.

Modern vehicles are increasingly built with improved materials, better quality control, and enhanced durability. As a result, many parts — such as suspension components, transmissions, braking systems, and chassis components — last longer, reducing replacement frequency. This leads to fewer repeat purchases over a vehicle’s lifetime, suppressing parts demand growth. Extended maintenance intervals for modern cars — sometimes stretched to 60,000–100,000 km or more before major part replacement — reduce the number of parts sold per vehicle per year. For parts suppliers and aftermarket distributors, this means slower consumption cycles and lower parts turnover per vehicle compared to older fleet demographics. Consequently, a restraint emerges for the Auto Parts and Accessories Market, because increased fleet size does not automatically translate into proportionally higher parts demand if vehicle durability continues improving.
