The factory specifications.

Paste.Read.Compare.

The factory’s numbers for the car the VIN actually is, not the trim the ad claims. Reading the specifications is free. No account. Dimensions, powertrain, capacities, standard equipment, each line with its source.

Hand the VIN to an agent that works for you and it pulls these same numbers: nothing here needs your signature, and what it reads is what you read.

    Seventeen characters

    The VIN, at specs.vin/{VIN}. Seventeen characters; the check digit verifies as you type, where the convention applies.

    Year, make, model, trim

    The VIN resolves to its year, make, model, and trim; the trim resolves to its factory numbers: dimensions, powertrain, capacities, standard equipment, each line with its source.

    Claim against record

    The ad’s claim against the record’s number. Where they differ, the delta is stated, not argued.

The wrong-trim spec.

“Tows 10,000 lbs” is a brochure line about a trim.

The record posts the number for this trim, before you pay a capability premium on equipment the car never carried.

  • ReadsThe options and packages the factory installed, retrieved.
  • AnswersCapability that came in on an option: a tow package, an off-road package.

Option-borne capability belongs to the as-built record, at sticker.vin. The spec is the car as designed; the sticker is the car as ordered. The seller reads the same page you do.

Questions with posted answers.

Are these the specs for my exact car?

The VIN resolves to its year, make, model, and trim; the numbers post for that trim, source stated. Options that change capability live on the as-built record, at sticker.vin.

What does it cost?

$0, posted above like every other number.

The ad claims a number this page doesn’t show.

Then the claim and the record differ: the delta is stated, not hidden. What the trim carries is on this page; what the seller added or asserts belongs to the ad, and the negotiation.

The spec is the first look.

Check the free faces first.

The free faces of the record read the same seventeen characters. They cost what this page costs: $0.

One spine of the catalog.

The catalog behind this page is posted at the pillar door.

The specification is one spine of the record’s crosswalk: the VIN resolves to the YMMTS hierarchy (year, make, model, trim, style) and every other face of the record joins through it. This door owns one job: the factory numbers, free.

An agent is a customer at this address on its own account: the motion is b2a.vin. Where an agent reads for a person, the receipt invariant holds: everything it does here survives being shown to them, and the numbers it returns are the numbers on this page.

For the agent you send.

The agent reads the same record you do.

Same two routes, three representations: the numbers never differ between them.
