What happens during a trade appraisal

Forty minutes, told from the side of the clipboard. The walkaround is not the part that decides the number — but it is the part that decides how much cushion gets built into the part that does.

The appraisal below is a composite. The car is invented, the timings are compressed, and no customer described here is a real person. The sequence, the checks and the reasoning are exactly how it goes on our lot. Every dollar figure is a round illustrative number chosen to make the arithmetic legible.

A car pulls onto the side of the lot on a Thursday morning. Six years old, mid-size, neither rare nor unwanted. The owner wants to know what we would give them for it. I take the keys and ask them to leave it switched off — I want to hear it start from cold if I can.

10:42 Standing back

Before touching anything I walk fifteen feet away and look down the side of the car at a low angle, with a straight line behind it — the edge of the building works. The reflection of that line across the doors tells me in four seconds whether a panel has been off. Straight here until the rear quarter, where it wobbles slightly.

Then around the whole car at that distance, twice. Gaps at the hood, gaps at the trunk, whether the two headlights have yellowed by the same amount. Mismatched headlight aging is one of the most reliable tells there is.

On the sheet

RR qtr: reflection wobble. Paint gauge here.

Headlights match. Gaps even F+R.

No overspray on door rubbers.

10:47 Corners and glass

Tires next, where more money moves than people expect. I read the date code on each sidewall and put a gauge in the tread at the inside, center and outside of every tire — a tire fine in the middle and finished on the inside edge is telling me about alignment, not about tires.

Glass: chips, cracks, and whether the windshield is original. An aftermarket windshield is not a problem in itself, but it is a question — and on a car with driver assistance it raises a second one about recalibration.

On the sheet

Tires: 3 matched, RF odd brand. 4/32 RF, 7/32 others.

Inner edge wear LF. Alignment + 2 tires min.

Windshield aftermarket. Chip low RH, not in sweep.

10:53 Door open

I open the driver's door and stand there without getting in. The first thing an interior gives you is its smell, and smoke and dog are the two that cost real money — neither reliably comes out, and both narrow who will buy the car. This one smells like a car.

Then the outer seat bolster and the pedal rubbers, compared against the odometer. Wear that runs well ahead of the mileage is not proof of anything, but it changes what I expect to find everywhere else.

Then the boring sweep people skip: every window, both mirrors, the sunroof through its full travel, every seat motor, the rear defroster, the climate control hot and cold, every fan speed. Individually small; collectively a large share of the reconditioning bill, and invisible in a photograph.

On the sheet

No smoke/pet. Bolster wear normal for miles.

Sunroof slow on close. Watch.

A/C cold. Rear defrost OK. Driver seat memory dead.

ONE KEY ONLY.

11:01 Cold start and under the hood

Start it and listen for the first ten seconds, not the next ten minutes. Then let it idle while I open the hood. Fluids for level and color, the underside of the oil cap, the valve cover for weeping, the belt for cracking. I run a hand along the lower edge of the radiator support, feeling for the roughness of a repair that was never painted.

Warning lights get read with a scan tool whether or not any are illuminated, because a recently cleared code leaves the readiness monitors incomplete — and a car cleared just before an appraisal is a car with something to say.

On the sheet

Clean start, no rattle. Coolant OK. Slight weep valve cover LH.

No codes. Monitors complete. Not cleared.

Rad support: factory. No repair.

11:08 Driving it

Five minutes is enough if the five minutes are chosen well. One rough patch of road with the radio off, listening for a clunk over the bumps. One firm stop from about forty, feeling the pedal and the wheel. One hard merge to make the transmission commit to a downshift. One tight full-lock turn in the lot, both directions, listening at the front axles. Then back with the windows down, listening to the car rather than to myself.

On the sheet

Trans shifts clean, no flare. Brakes straight, slight pulse.

Clunk over bumps RR — sway link?

No CV noise at lock.

Then I go inside, and the walkaround stops mattering

Everything above took thirty minutes and produced a list of problems, not a number. The number comes from four questions asked at a desk, and I would rather show you those than pretend the clipboard is where the decision lives.

1.What does this car retail for, here, this month?

Not nationally — within driving distance of this lot, right now. How many are listed nearby, at what prices, how long have they been sitting, and is this color and trim one people call about. Call it $14,500 for a clean one.

2.What has to happen before I can put it out front?

From the sheet: two tires and an alignment, the sway link, the seat motor, the sunroof looked at, a full detail, a second key cut and programmed. Call the list $1,400. If it needs paint, that stops being small fast.

3.How long will it take to sell, and what does that cost?

Money tied up in a car costs money every day it sits, which is why a car standing ninety days gets repriced instead of defended. Three weeks is cheap; a color nobody asks for in a slow month is not. Call it $250 for a normal stay, plus the lot's overhead share.

4.What could I be wrong about?

This is the biggest line and it is never itemized. The sunroof that is "slow on close" might be a track and a lubricant, or a motor and a headliner out. I cannot open the transmission, so I am pricing the possibility that it is not as good as it drove for five minutes.

Every appraisal carries a cushion for the unknown, and its size is the single largest difference between a trade number and a private-sale price. A private buyer takes that risk themselves and gets paid for it in the discount they negotiate. I take it on, so I subtract it up front.

$10,800

Illustrative trade offer on a $14,500 retail car

Retail target $14,500, less about $1,400 of reconditioning, less carrying and overhead, less the cushion for what I cannot see, less the margin that keeps a service bay staffed. That is how a trade number is reached — not by any gamesmanship about your attachment to the car.

Why it is lower than a private sale, plainly

Because a private buyer pays for a car and I pay for a project. They inherit the tires, the sway link and the one key; I fix them. They accept the risk that the transmission is tired; I price it.

On an ordinary car in ordinary condition, you will do better selling it yourself, and we would rather say so than buy your car badly. What a trade buys is the whole of the other column on that scorecard — no listing, no strangers, no payoff choreography, done today. Some weeks that is worth two thousand dollars and some weeks it is not, and only you know which week it is.

Four things that genuinely move the number, and one that doesn't. Bring both keys. Bring the service records. Fix or diagnose any warning light so the cushion for it can come off. Tell us about the accident before we find it, because a disclosed repair is priced and an undisclosed one is discounted twice. What does not move it: a fresh wax — though a filthy car does hurt, because it makes me assume the maintenance was handled the same way.

Composite account. The appraiser, the customer and the vehicle are invented for this article and the figures are round illustrative numbers, not a record of any transaction, valuation or auction result. Reconditioning costs, retail values and holding costs vary widely.
