Time to Line: The One Number That Runs Your Used-Car Lot

Ask ten used-car managers what their time to line is and you'll get ten shrugs. Ask them what it costs and you'll get silence. Yet no single number tells you more about the health of a used-car operation.

What is time to line?

Time to line (T2L) is the number of days from when you acquire a vehicle to when it is front-line ready: inspected, reconditioned, priced, photographed, and available to sell. Not "in the shop." Ready.

Everything in between (inspection, parts, repair, sub-let, detail, photos) is recon. T2L is the clock on all of it.

Why it decides your gross

A used car is a depreciating asset with a meter running. Every day in recon costs you three ways:

• Floorplan interest. You're paying to hold inventory you can't sell.
• Depreciation. Market values drift down while the car sits.
• Opportunity cost. A stall in recon is a stall in turn, and turn is where used-car money is made.

Industry benchmarks put the daily holding cost of a used unit at $32 to $40 a day. Cut your average T2L from 12 days to 7, and on 60 cars a month you've freed up thousands in carry cost, and put those units on the line five days sooner, while they're still fresh to the market.

How to calculate it

For each unit:

T2L = date front-line ready − date acquired

Then average it across your inventory. But the average hides the story. Two numbers matter more:

• Time-in-stage shows where the days actually pile up, and it's almost always parts or a specific repair queue.
• Your slowest 10% is where the carry cost lives. A handful of 30-day cars will wreck an otherwise healthy average.

What's a good target?

It depends on your mix, but as a rule of thumb:

• Under 5 days is excellent, and you're running a tight lane.
• 5 to 10 days is solid, with room to tighten.
• 10+ days means you're leaking gross, and there's a bottleneck you probably can't see yet.

How to actually drive it down

You don't improve T2L by pushing people to "go faster." You improve it by making the delays visible:

1. Track time-in-stage so the bottleneck raises its hand.
2. Kill the parts black hole with ETAs and back-order alerts.
3. Put a name on every unit so nothing is owned by nobody.
4. Approve estimates before work starts, so nothing gets redone.

That's the whole playbook, and it's covered step by step in The Used-Car Recon Workflow.

The stores that win on used cars aren't the ones with the best buyers. They're the ones that get metal to the line before it goes stale. ReconPath puts real time-to-line reporting on every unit and every stage, so you can prove the number is dropping. See it on your own inventory.
