How Long Should Recon Take? Every Published Benchmark, Sourced

The Short Answer

Ask what a used car's recon should take and three answers come back. The published targets say three to five days. The published estimates of what stores actually do say seven to ten. And the best-run stores are described as finishing in 24 to 72 hours.

What you won't find is an independent survey that measured recon time across dealerships. The number you see quoted most often is a target from one company, an estimate from one expert, or data from one vendor's customers. This article lists what has been published, says who published each figure and how it was reached, and then shows how to build the benchmark that matters: your own.

What Recon Is Supposed to Take: Published Targets

These are goals, not measurements of what dealers achieved.

Two of the three come from Cox Automotive, the owner of Manheim and vAuto, so they're closer to one view than to three. The five-day figure is a software company's recommendation for its own customers.

You'll sometimes see a three-day benchmark credited to NADA. The published source we found for it is Cox Automotive's 2018 article, not an NADA document.

What Stores Actually Report

These figures describe what stores do, and each one has a limit worth knowing before you repeat it.

Read together, these say a typical store takes about a week to ten days and a well-run one takes three to five. That fits the targets above. It is still opinion and vendor data, not measurement. A store that quotes "the industry average is ten days" in a meeting is quoting one consultant's estimate.

Where the Time Goes

We found no independent study of where recon time is spent, or of how much of it is work and how much is waiting. The only published stage-level numbers come from a 2021 column in WardsAuto by Dustin Jones, a performance manager at Rapid Recon. He wrote that he had studied recon data from 66 dealerships, 33 faster and 33 slower.

• The detail step averaged 4.7 days at the slower stores and 1.7 days at the faster stores, nearly three times as long. (Our arithmetic.)
• Stores that used step notifications met their time-to-line goals 64% of the time.

It's vendor data from a vendor's customers, and the column doesn't explain the gap. It does show that the same step can take very different lengths of time from one store to the next, which is a reason to time each stage in your own store instead of only the total.

Why the Numbers Don't Line Up

A "three-day" and a "ten-day" figure can both be correct and still describe different things, because stores and vendors start and stop the clock at different points. The glossary entry for days in recon puts it this way: some stores start the clock at acquisition, some when the vehicle arrives on site and some when inspection begins, and they stop it at different points too.

• Start. The purchase or trade-in date, the day the vehicle arrives on site, or the day inspection begins.
• Stop. Repairs finished, detail finished, photographed, or listed online. Where a store draws the front-line ready line changes the number by days.
• Which vehicles. Every unit, or only the ones that went through the shop? Cars sold wholesale or pulled for a long parts wait change an average a lot.

Before comparing your number to any figure in this article, check that both use the same start, the same stop and the same set of vehicles. The glossary entry for time to front line sets out the usual definition.

The Inventory Benchmarks Recon Sits Inside

Recon time matters because it comes out of the window a car has to sell. These are the published inventory benchmarks that window comes from.

Twelve turns a year works out to about 30 days from acquisition to sale (365 divided by 12; our arithmetic, as an illustration). Against that 30-day window, a three-to-five-day recon uses about a tenth to a sixth of it. A ten-day recon uses a third. NADA's data shows why that matters: about half of used vehicles sell in their first 30 days, and the days a car spends in the shop are days it can't be shown.

What those days cost in floor plan interest, depreciation and overhead is worked through in The True Cost of a 10-Day Recon Cycle, and you can run your own numbers in the recon cost calculator.

Finding Your Own Number

Because no independent average exists, the useful benchmark is the one you measure. A month of data is enough to start.

1. Write down the clock. Decide which event starts it and which stops it, and use the same two events every time. Nothing else matters if this changes from month to month.
2. Time every vehicle, stage by stage. Record the date each vehicle enters and leaves each stage for 30 days: inspection, mechanical, body, sublet, detail, photos. The total tells you where you are. The stages tell you why.
3. Look past the average. One car stuck for 40 days on a parts order can double an average. List the slowest vehicles individually, then look at the typical car.
4. Separate light recon from heavy. A car that needs a detail and an oil change shouldn't be held to the same number as one that needs body work and tires. Many stores set a target for each.
5. Set a target slightly ahead of today's number. If you run nine days, aim for seven before aiming for three. Copying a benchmark from this article without knowing your own starting point sets a target nobody believes.
6. Re-measure every month. The point is the trend. A number that doesn't move needs a look at the stage where cars wait longest.

Why the Average Misleads: A Worked Example

Here are ten vehicles from an imaginary store, in days from the start of the clock to front-line ready. (Made-up numbers, for illustration.)

• The average is 70 days ÷ 10 vehicles = 7.0 days.
• The middle vehicle (the median, halfway between the fifth and sixth cars) is 4.5 days.
• Take out vehicle 10 and the average of the other nine is 4.3 days.
• That one car, stuck on a part for a month, is 31 of the store's 70 vehicle-days, or 44%.

Reported as "a seven-day average," this store sounds like it's sitting in the middle of the published estimates. Reported fully, it has a typical car at about four and a half days and one car that needs a different kind of attention. The two problems have different fixes, and an average alone hides which one you have.

This is the work a whiteboard or spreadsheet makes tedious. In Vehicle Recon Tracker, every status change is recorded with who made it and when, so the days in each stage come straight from the status history. The Reports page shows average recon times, the average time in each status and a bottleneck analysis, and the dashboard shows color-coded age warnings at 7 and 14 days. The seven steps to bring your time to front line down cover what to change once you can see where the days go.

The Bottom Line

Three to five days is the published target, and the best stores are described as faster. Seven to ten days is what experts and vendors say is typical. None of it was measured independently, so treat each figure as one source's view and check what it counts. Then measure your own stages for a month. That number is the one that will change how fast cars reach the front line.

Frequently Asked Questions

How long should recon take on a used car?

Published targets are three days (Cox Automotive, 2018) to five days (Rapid Recon, 2025), and Dale Pollak described the best dealers as finishing in 24 hours or less (Cox Automotive, 2016). What stores report is longer, about seven to ten days. Your own measured number is the one to manage against.

What is the average recon time in the US?

No independent measurement exists. Estimates include about seven days (a vAuto executive, 2020), around ten days (a consultant, 2026), and 13.2 days across Rapid Recon's customers early in the 2020 pandemic. Each comes from an expert or a vendor, not a survey of dealers.

Is there an official NADA recon time benchmark?

We found none. The three-day figure sometimes credited to NADA appears in Cox Automotive's 2018 used-car KPIs article. NADA does publish inventory turn guidance: twelve used-vehicle turns a year.

Is recon time the same as days in inventory?

No. Days in inventory, or vehicle age, keeps counting until the car sells. Recon time stops when the car is ready for sale. It is the part of a car's age spent unavailable to buyers. See time to front line in the glossary.

Should every vehicle have the same recon target?

The published targets are single figures, but cars need very different amounts of work. Many stores set separate targets for light and heavy recon and track the slowest vehicles on their own. Measure each type for a month before you set the numbers.
