Independent VIN appraisal record

The dealer knows what your car is worth.
Now you do too.

Before you take a trade-in offer, see your car the way the appraiser sees it: the history they'll pull, the market range they'll check, and the fair offer window — every deduction printed. No subscription needed.

How an appraisal actually works

Three things happen before any offer.
We do all three for you first.

No. 01 Ink drawing of a magnifying glass over a VIN plate

They pull the file.

Title brands, theft records, the odometer trail — the NMVTIS file every dealer checks before quoting you. Your report shows you the same file, spelled out.

No. 02 Ink cutaway drawing of a four-cylinder engine

They know the patterns.

Appraisers know which engines eat oil and which transmissions die young. Our known-issues layer prints the documented patterns for your exact year and model — with the NHTSA complaint counts to back them up.

No. 03

They run the math.

Retail average, minus reconditioning, minus margin, minus selling costs. That's the whole trick. We print every line of it and grade the offer in your hand against the result.

The published formula

No black box. The math is on the page.

Fair trade-in window

Sample: 2015 Nissan Altima 2.5 SV · 88,000 mi · good condition

Retail market average (this trim, this mileage)$9,800
Reconditioning (tires + CVT service)−$700
Dealer margin (~10%, our rule of thumb)−$980
Selling costs (photos, lot time)−$500
$7,400 – $8,200

A fair offer lands inside the window. The numbers shift with condition and market — the shape never does.

The dealer's offer
$6,800
Lowball

$600 under the bottom of the fair window with a clean record — counter with the window, or get a competing cash offer.

Every deduction, printed.

Estimator sites hand you one mystery number and sell your phone number to four dealerships. We show the working: what the retail range is, what each deduction is for, and where the window lands. If a line looks wrong for your car, you can see it and argue with it.

Then we grade the offer in your hand.

Bring the dealer's number. It gets stamped LOWBALL, FAIR, or STRONG against the window — with the dollar gap, so you know exactly how much is on the table.

We show receipts

Not “trusted by thousands.”
Public records, exact counts.

Every claim in our guides traces to a public source you can check yourself — mostly NHTSA's complaint and recall databases. Here's the kind of number we mean.

Straight pricing

Pay per car. Never per month.

One report before you walk into the dealership can be worth thousands on the trade. We charge per car, not per month.
