How do I buy a used car I found online — from a dealer, Craigslist, or an auction listing?

You already found the car. The way to buy it is to start from the one thing that never changes no matter where it was listed — the VIN — and let a single deal record carry the rest. Paste the VIN into buy.vin and the car decodes, the deal record opens, and the whole purchase runs from there: pre-approval, out-the-door price, insurance, lien payoff, notarized paperwork, funding, and delivery. It works the same whether the listing lives on a franchise dealer's website, a Craigslist post, a marketplace app, or an auction run list, because the record is keyed to the car, not to the seller's platform. At every step it tells you your distance to done — "you're two steps from done: insurance, then delivery" — so the purchase stops being a gauntlet you carry and becomes a checklist the record carries for you.

That is the shift worth understanding. Buying a used car has always been a stack of separate errands — get financed, work out the tax and fees, bind insurance, pay off the seller's loan, transfer title, arrange to get the car home — and each errand has historically lived with a different party who could see the others' numbers when you could not. The desk's advantage was never that it did the work; it was that it held all the facts in one place while you held none. Buying by VIN inverts that. Everything about the car — its history, its market value, its exact out-the-door number, the coverage priced to it — resolves at one address, and the dealer on the other side reads the same page you do.

Why the VIN is the right starting point

A listing is a description of a car; a VIN is the car. Once you have the seventeen characters, the record can decode the year, make, model, and trim, pull the vehicle history, place it against the market values, and compute the taxes and fees to your registration state — none of which depend on which website the seller used. This is why "any source" is not a marketing line but a structural fact: the moment you hold the VIN, the source has done its only job. A car you found on a dealer's site, a car in a Craigslist ad, and a car on an auction run list all enter the same record the same way.

That also means you can read the car before you commit to buying it, which is the honest order of operations. Check the history and any open recalls first. Read the market value so you know whether the asking price is in range. Pull the out-the-door number for your zip so the tax, title, and DMV fees are known — not sprung after you've said yes. All three of those answers are free to read at their own addresses, and the deal record picks them up unchanged when you're ready to proceed.

The seven steps, and where a human actually has to show up

The purchase itself is a seven-step checklist on one event-sourced deal ledger. Each step is a state on the record, each states how many steps remain, and each ends on the specific order line it fills:

1. Verify — the record opens; history, recalls, value, and the out-the-door number by state are read before any money moves.
2. Pre-approve — financing starts from the VIN with a soft pull first; the single hard pull happens only when you authorize the application. Bring your own bank's approval and it's recorded here as cleared.
3. Insure — coverage is quoted from the VIN because the car is already known; existing coverage counts.
4. Notarize — where a state requires it, a power of attorney keyed to the VIN authorizes the title and registration filing. Whether your state requires this is stated before step one.
5. Sign — the document stack is signed online, and the buyer's order is itemized so nothing appears for the first time at signature.
6. Settle — one payment clears the one out-the-door total; the seller's lender is paid off at settlement.
7. Deliver — two zip codes produce the transport quote, and every mile of transit lands on the record.

The human appears at exactly four of those steps — authorize the credit pull, appear before the notary, sign, and pay. Everything between can be walked by an agent working for you. The instrument is identical either way: the same states on the same record, readable as typed data, so nothing an agent does is hidden from you when you look.

The number you commit to, and what it costs

The out-the-door total is shown whole before you commit — vehicle price, then taxes, title, and DMV fees, then financing, insurance, and delivery each on its own line, minus any trade, plus the deal fee — with the exact figures computed to your state and zip. Nothing is introduced after commitment. The service fee for running the checklist is flat: $349, the same for every deal type, itemized on the buyer's order and charged in no state before that state's requirements clear. It is not a percentage of the car's price, and financing, insurance, and transport are priced separately, each on the same record. Where the fee covers deal configuration, e-signature, the notarized power of attorney, title and registration handling, and delivery coordination — the paperwork gauntlet, in other words, run once and shown to you.

One honest limit: the end-to-end close opens state by state as each state's broker requirements are cleared, so buying entirely through this page may not yet be available where you register. Even where the full close isn't live, every instrument already answers at its own address today — the record, the value, the out-the-door number, the pre-approval, the coverage — free to read before you decide.

Read the car before you buy it: vhr.vin for its full history and open recalls, values.vin for what it's actually worth. Then paste the VIN at buy.vin and let the record do the rest.
