For owners

The history you paid for should pay you back at sale time.

1ownr turns every receipt, invoice and service note into a verified record attached to your VIN — so when you're ready to sell, you have proof instead of promises.

Why 1ownr

Because a well-documented car is worth more than one with a story.

Buyers haggle on doubt

A clean, dated paper trail answers 'how do I know?' before the question is asked. That confidence often converts to a better offer.

Records get lost, VINs don't

Attach every service event to the VIN and the history stays with the vehicle across shops, dealers and owners.

One link, no attachments

Stop forwarding a folder of PDFs. A Passport link shows buyers exactly what they need to see — and nothing they shouldn't.

Built for real cars, real people

Classic cars, daily drivers, project cars — if you care about what it's worth, the record matters. 1ownr keeps it simple.

Auction sellers

Documented history sells for more.

On Bring a Trailer and Cars & Bids, the comment thread runs on history. “Any service records?” gets asked on every listing, and a folder of phone photos posted mid-auction never reads as proof. A 1ownr Vehicle Passport is one link — dated records, mileage at each service, receipts attached, in order — that you drop into your listing description and answer with once. Bidders see continuous ownership care instead of a gap, and you stop bidding against your own missing paperwork.

For the seller to paste into their listing

Full service history: [1ownr Passport link] — every record since I bought it, dated and receipted.

Why it works

Verifiable, not asserted

Records are dated and mileage-stamped as they're entered, not assembled the week of the sale.

One link, not forty photos

Bidders read a single ordered page instead of scrolling receipts in the comments.

Removes the discount

Unknown history is the cheapest reason to bid low. Documented history takes it off the table.
