Vehicle Reconditioning Glossary
Plain definitions of the terms used in used-vehicle reconditioning, from time to front line to curtailment. Where a figure is given, the source is linked beside it.
- ACV (actual cash value)
-
The dealership’s appraised value of a vehicle it takes in, usually a trade-in: what the vehicle is actually worth to the store in cash, separate from any trade allowance shown on the customer’s deal. Appraisers account for the recon the vehicle will need when they set it, so recon that runs over the appraisal’s estimate comes out of the vehicle’s gross.
- Aging inventory (also aged units)
-
Used vehicles that have been in stock longer than the store’s target. Most stores count a vehicle’s age from the day it was acquired, so days spent in recon count toward it, and many review inventory in 30-day bands (0–30, 31–60, 61–90 and over 90 days). Stores usually have a policy for repricing or wholesaling vehicles that pass a set age.
Vehicle Recon Tracker’s dashboard color-codes vehicles in recon at 7 and 14 days.
- Curtailment
-
A required payment toward the principal on a floor-planned vehicle that hasn’t sold after a set number of days. The lender’s agreement sets when curtailments start and how much each one is. A vehicle that sits in recon moves closer to its first curtailment before it has reached the lot.
- Days in recon
-
How long a vehicle spends in the reconditioning process. Dealers and software vendors start and stop this clock at different points. Some start it at acquisition, some when the vehicle arrives on site and some when inspection begins; some stop it when the work is finished and others when the vehicle is front-line ready. Before comparing a published figure with your own, check how it was measured. See also time to front line.
- Days’ supply
-
How many days the inventory in stock would last at the recent sales pace: units in stock divided by average daily sales. Cox Automotive, which bases its figure on the estimated daily retail sales pace for the most recent month, put the national used-vehicle days’ supply at 44 days in August 2026.

- Depreciation
-
The fall in a vehicle’s market value over time. Used values move with the market and the season, so there is no fixed daily rate. One reference point: Manheim’s index of wholesale values for three-year-old vehicles fell 1.8% in August 2026, against a typical 0.6% for that time of year. A vehicle loses value while it sits in recon just as it does on the lot.

- Floor plan (also floor plan financing, flooring)
-
A revolving line of credit a dealership uses to finance its inventory. Each vehicle is a separate advance against the line, secured by the vehicle itself, and is paid off when that vehicle sells. Floor plan lenders include banks, manufacturers’ finance companies and independent floor plan companies.
- Floor plan interest
-
Interest charged on each vehicle’s floor plan balance for every day it is outstanding. Rates usually float with a benchmark, such as the prime rate or SOFR, plus a spread. A daily estimate for one vehicle is its floor plan balance × the annual rate ÷ 365.
For reference, Sonic Automotive reported a weighted-average rate of 6.50% on its used vehicle floor plan for 2025, and AutoNation 5.2% at December 31, 2025. AFC, which provides floor plan mainly to independent used vehicle dealers, earned 18.1% on its receivables in 2025, interest and fees combined.

- Front-end gross
-
The profit on the sale of the vehicle itself: the selling price minus the vehicle’s cost, where the cost includes what was spent reconditioning it. It leaves out back-end income from finance and insurance products. For reference, Sonic Automotive reported used retail gross profit of $1,514 per unit at its franchised dealerships for 2025, before finance and insurance income.

- Front-line ready (also retail-ready, lot-ready)
-
A vehicle that has finished reconditioning and can be shown, test-driven and sold: repairs and detail done and, in most stores, photographed and listed online. Where a store draws this line decides where its time to front line clock stops, so it is worth writing the definition down.
- Holding cost (also carrying cost)
-
What it costs to keep one vehicle in inventory for one more day. Floor plan interest and depreciation are the obvious parts; some methods also spread the used department’s fixed overhead across the units in stock. Overhead differs so much between stores that holding cost is a store’s own number, not an industry one. Two worked examples from NCM Associates consultants, published in WardsAuto, came to $17.53 a day (2004) and $52.12 a day (2008).
The recon cost calculator works out the floor plan and depreciation part for your store.

- Internal labor rate
-
The hourly rate the service department charges the used-car department for recon work on internal repair orders. Stores set it differently: some charge their customer-pay rate, some a discounted rate, some cost plus a margin. Whatever the rate, it moves profit between the two departments and changes the recon cost recorded against each vehicle.
- Inventory turn (also turn rate)
-
How many times a year a store sells through its average used inventory: annual used retail sales divided by the average number of units in stock. Cox Automotive’s used-car KPI guide put 12 turns a year as good and 16 as great. Days in recon count toward a vehicle’s time in stock, so faster recon helps turn.

- Pack (also dealer pack)
-
A fixed amount a dealership adds to a vehicle’s cost on the deal, often to cover overhead such as reconditioning, lot expenses or advertising. Because it raises the recorded cost, it lowers the gross that sales commissions are paid on. Each store decides its own pack and what it covers.
- PDR (paintless dent repair)
-
Removing a dent by working the metal back into shape from behind the panel, without filler or repainting. It suits small dents and dings where the paint isn’t broken. Many stores sublet it to a PDR technician.
- Recon approval (also estimate approval)
-
The step where a manager approves the estimated recon work and spend before it starts. Many stores set a dollar limit below which work is pre-approved, so only larger estimates wait for sign-off. A vehicle waiting for approval doesn’t move until someone looks at it, which makes this step easy to lose days in.
In Vehicle Recon Tracker, the built-in Pending Approval status emails the people you choose when a vehicle needs sign-off.
- Recon cost per vehicle
-
Total reconditioning spend (parts, labor, sublet work and detail) divided by the number of vehicles completed in the period. It is worth tracking separately by source, such as trade-ins and auction purchases. It covers only what was spent on the vehicles; the cost of the days they spent in recon is holding cost.
Vehicle Recon Tracker shows the average per unit on the dashboard. See recon cost tracking.
- Reconditioning (also recon, get-ready)
-
The work that gets a used vehicle ready for retail sale after the dealership takes it in: inspection, mechanical repairs, body and paint, detail and, usually, photos for the online listing. Some stores call it the get-ready process. What is vehicle reconditioning? covers the stages in more detail.
- Repair order (RO) (also internal RO)
-
The document the service department opens for work on a vehicle. Recon work goes on an internal RO, billed to the used-car department rather than to a customer, so its cost becomes part of the vehicle’s cost.
- Stage dwell time
-
How long a vehicle spends in one stage of recon, such as waiting for parts or at the body shop, before it moves on. Averaged by stage, it shows where vehicles wait longest, which is usually the bottleneck. Vehicle Recon Tracker’s reports show the average time in each status.
- Sublet
-
Work the dealership sends to an outside vendor instead of doing it in-house, such as paintless dent repair, paint and body, wheel repair, glass or upholstery. The vendor’s invoice becomes part of the vehicle’s recon cost. Sublet work runs on the vendor’s schedule, so vehicles out at a vendor need someone following up. See sublet and vendor email.
- Time to front line (also time to line, T2L, TTF)
-
The time from when a dealership acquires a used vehicle to when it is front-line ready. It is the most common measure of how fast recon runs, but stores and vendors start and stop the clock at different points, so compare figures only when they were measured the same way.
Cox Automotive’s 2018 used-car KPI guide set 3 days as the target for mechanical and cosmetic reconditioning time. We haven’t found a current, measured industry-wide average: most published figures are targets or software vendors’ own customer data.

- We-owe (also due bill)
-
A written record of something the dealership has promised to do or supply after the sale, such as a second key, a repair or a detail. The customer signs it with the deal, so both sides know what is owed.
- Wholesale
-
Selling a vehicle to another dealer or through an auction instead of retailing it. Stores usually wholesale vehicles that don’t fit their retail standards or would cost more to recondition than the retail price would cover.
