Own the record, not just the car.
Your car is an asset — the Vault is where you treat it like one. A secured home for what you own and what you've built, where receipts and documentation become defensible value, not a shoebox of paper. Two vaults, one encrypted spine.
Two ways to protect value.
For the car you're building.
Value the car, add every receipt, and watch documented work become a defensible value story you can hand to the next owner. For the daily driver and the weekend project as much as the concours car — nothing like it exists for collectors.
For what you can't afford to guess about.
A secured, cross-asset portfolio of record for serious collectors — auto-revalued, provenance-documented, and defensible enough for estate, insurance, and wealth conversations.
A garage remembers your car. The Vault values it.
Plenty of apps will store your receipts and photos — that's the easy part, and it's where they stop. The Vault is the valuation layer that sits on top of your records: it starts there and adds the thing that actually protects an asset — a defensible number.
It values — it doesn't just store
Every car and every build is positioned against real comparable sales, not filed away. A folder of PDFs isn't a value; a comp-backed number is.
Cost kept honest from value
Two ledgers, visibly apart: what you spent, and what the market pays for it. Receipts prove cost and scope — never quality, and never a dollar of value on their own.
Our AI adjudicates — it never invents
We grade the strength of your evidence. We don't generate a story for your car — a made-up history is the last thing you want attached to a car you'll one day sell.
Private by design, never social
Your collection is firewalled and encrypted — never mapped, listed, or turned into a public feed. What a serious owner shares is their choice, item by item.
Everything you own, valued and secured.
One encrypted dashboard for a whole collection — each asset auto-revalued as the market moves, with the provenance and paperwork that protect it. Built for collectors, family offices, and the people they trust with the details.
Your receipts, finally worth something.
The hardest cars to value are the ones people build. The Build Vault turns your receipts into a documented, methodology-backed value story — and keeps what you spent honestly separate from what it's worth.
Start from the car
Value the base car through the Parclines gateway — the anchored, market-based shell value.
Import your receipts
Upload invoices and records. We store the actual files, read them, and organize the build.
See the real effect
We separate what you spent from what it's worth — job by job, honest about the gap. Cost never equals value.
Hand over proof
Export a ZIP packet — cost-basis schedule, every receipt, a machine-readable manifest — that travels to the next owner.
1973 Datsun 240Z — owner build
Base car value $40,000. Below is a real run through the Parclines build engine — two ledgers kept visibly apart.
Selling
Hand the next owner a complete, credible provenance packet — and defend your ask with documentation, not a pile of paper.
Tax time
A clean cost-basis schedule, capital improvements separated from maintenance — ready for your CPA. (Not tax advice.)
Estate & insurance
Defensible, methodology-backed valuations and provenance — what an estate, appraiser, or insurer actually needs.
