Overall Length of Rental (LOR) for collision-related rentals in Q4 2025 was 15.9 days, a 0.6-day decrease from Q4 2024, according to Enterprise Mobility data released Feb. 5. 

While LOR continues to decline from the post-COVID highs seen in 2022 and 2023, Q4 2025’s decline was more moderate than those in Q4 2024 and 2023. In Q4 2024, the overall LOR decline was 1.3 days from the previous year’s quarter. And in Q4 2023, the LOR declined from Q4 2022 by a full day. 

The post-COVID effects of vehicle production and supply chain issues had an outsized impact on LOR in 2022 and 2023.

When comparing 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.

State-By-State LOR Trends

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

• North Dakota had the lowest LOR at 11.7 days, with Hawaii (12.2 days) and Iowa (12.9 days) next-lowest.

• Nebraska had the highest overall decrease, with its 13.4 days representing a 2.7-day decline, closely followed by Colorado with a 2.6-day decline (17.0 days). 

• Seven additional states had declines of more than a full day, with 15 others seeing declines of at least a half-day.

Experts Offer Detailed LOR Analysis:

Several trends could be contributing to a modest decline in the length of rental. 

First, the average hours worked each week by the industry’s production employees have remained at historically high levels through October, according to government data. In October, the average production employee worked 38.9 hours per week, more than in any October in the eight-year period prior to the pandemic.

Greg Horn, PartsTrader’s chief industry relations officer, offered some analysis, comparing parts data to LOR: 

“PartsTrader’s data shows a 2-day decline in median delivery days for all part types. As OEM parts comprise the largest portion of parts on a repair estimate, OEM-only median delivery days were just over 1 day lower than Q4 2024, aligning with the reduction in LOR from Enterprise.”

John Yoswick, editor of the weekly CRASH Network newsletter, offered some insights from data he’s received: 

“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.”

Ryan Mandell, vice president of strategy and market intelligence for Mitchell International, added: 

“While supplements will still be processed over the next several months, early data indicates continued strength in inventory of alternative parts, with the percentage of parts dollars attributed to alternative parts (aftermarket, recycled, remanufactured) rising 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. This number will likely end lower than its current level, but we still expect the result to be about half a point higher than the same time period the previous year,” Mandell said.

Yoswick also added: “Perhaps also helping speed repairs: The CRASH Network survey also found that the percentage of shops with employees doing ADAS calibrations in-house has continued to grow. Nearly 3 in 10 shops (29%) said doing the work themselves in-house is the most common method they use, up from 22% in 2024. While 35% of shops back in 2022 said they most often sublet calibration work to a dealership, that has continued to decline significantly to just 10% of shops today.

“But as with length of rental, these changes aren’t driving several other metrics down sharply. The scheduling backlog at shops across the country in October remained essentially the same as it had since April, according to the ‘Who Pays for What?’ survey of more than 500 shops conducted by Collision Advice and CRASH Network. The average backlog of work for Q4 stood at just 1.7 weeks, or half a week less than in the same period a year earlier. But it is the same level recorded in the fourth quarter of pre-pandemic 2017, 2018, and 2019,” Yoswick said.

While LOR continues to decrease from post-pandemic highs, ongoing market and economic conditions could impact future results. 

Mandell added, “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.”
