LOR reaches 15.9 days, just over half a day decrease compared to Q4 2024

Overall length of rental (LOR) for collision‑related rentals in Q4 2025 was 15.9 days, a 0.6‑day decrease compared to Q4 2024, according to Enterprise Mobility.

The newest LOR report states that while there is a downward trend from post‑COVID peaks in 2022 and 2023, the Q4 decline was more gradual than in the same quarters of the past two years. In Q4 2024, the overall LOR decline was 1.3 days from Q4 2023. And in Q4 2023, the LOR declined by one day compared to Q4 2022.

“We’ve previously discussed the outsized impact on LOR in 2022 and 2023, given the post-COVID effects of vehicle production and supply chain issues,” the report states. “When we compare Q4 2025 to Q4 2021, LOR is 1.1 days lower, but with Q4 2025 to Q4 2020, overall LOR is currently 2.8 days higher.”

Rhode Island and West Virginia recorded the highest overall LOR at 19.9 days, followed by New Mexico at 19 and Kentucky at 18.9.

North Dakota had the lowest LOR at 11.7 days, followed by Hawaii (12.2) and Iowa (12.9). The District of Columbia’s 1.4-day increase was the highest compared to Q4 2024, bringing its overall LOR to 13.

Enterprise named several trends that could be contributing to a modest decline:

• • The average hours worked each week by the industry’s production employees remained historically high through October, reaching 38.9 hours — more than in any previous October of the eight years before the pandemic.
  • PartsTrader data shows a 2-day decline in median delivery days for all part types, with OEM-only median delivery days down by just over one day from Q4 2024
  • Early Mitchell International data indicates continued strength in alternative parts inventory
  • CRASH Network “Who Pays for What?” survey data shows that the number of shops performing in-house ADAS calibrations has continued to grow, with 29% saying doing the work in-house is the most common method they use, up from 22% in 2024.

Ryan Mandell, Mitchell’s vice president of strategy and market intelligence, states in the report that the percentage of parts dollars attributed to alternative parts (aftermarket, recycled, remanufactured) rose to 40.9%, up from 39.2% in Q4 2024.

“Additionally, the percentage of parts repaired continues to increase, with Q4 2025 currently sitting at 16.3% compared to 14.6% in Q4 2024,” he said. “This number will likely end lower than its current level, but we still expect the final result to be about half a point higher than the same time period the previous year.”

John Yoswick, CRASH Network editor, added, “Parts-related challenges seem to have eased somewhat. A CRASH Network survey in late 2025 found that nearly half of shops (45%) said they were having somewhat or significantly fewer parts problems — such as back-ordered parts, or parts locating issues — than they were a year earlier. For another one-third of shops, parts challenges may not have eased, but at least they hadn’t gotten worse.”

Yoswick also said the average backlog of work in Q4 was 1.7 weeks, or half a week less than the same period in 2024 and the same level recorded in the fourth quarters of pre-pandemic 2017, 2018, and 2019.

Drivable LOR for Q4 2025 was 14.8 days, a 0.5-day decline from Q4 2024. Non-drivable LOR was 21.4 days, a 0.8-day
decline from Q4 2024.

Total loss LOR was 14.2 days, a 0.6-day drop from Q4 2024.

The report notes that ongoing market and economic conditions could impact future LOR data.

“The average deductible rose by 2% in Q4 2025 compared to Q4 2024 ($811 vs $795), indicating continued consumer concern about the affordability of auto insurance and likely leading to fewer smaller dollar claims being filed,” Mandell said.
