01The File Behind the Build

Every receipt.
Every part.
Every version of the car.

Garage Files is the record system for cars people actually build. One file for the receipts, parts, service, media and ownership trail — so the story of the car survives the next sale.

02The Problem

Glove box. Group chat. Camera roll. Three shops. One folder nobody can find.

A built car has a richer history and worse records than a stock one.

Years of work end up scattered across text threads, invoices in a drawer, a shop's internal system, and eleven thousand photos on a phone. Nothing is connected. When it's time to sell, the owner is reconstructing five years from memory, and the buyer is asked to take it on faith.

Proof is missing

The work was real. The paperwork can't show it.

Trust is fragile

Buyers discount what they can't verify.

Value leaks

A messy file costs real money at sale.

Invoices, a dyno printout, handwritten shop notes and a phone on a workbench

Documentation is messy, human, and worth more than people think.

Reference frame — workbench, receipts, dyno sheet

03What It Does

Forward it once.
It's filed forever.

  • 01 CentraliseReceipts, invoices, titles, tunes, dyno sheets.
  • 02 Log the buildParts in, parts out, version by version.
  • 03 Keep the mediaPhotos and clips attached to the work they show.
  • 04 Track serviceMileage, intervals, who touched what.
  • 05 Share cleanlyA buyer link that answers questions before they're asked.
  • 06 Hand it overThe file transfers with the car.
04The Build File

Not a folder. A record of the car.

Structured around how builds actually happen: versions, not chapters. Every part, receipt and photo lands on the moment it belongs to. Private by default, shareable the second you decide to sell.

05Ask The File

It only knows what your car can prove.

The assistant reads the owner's own uploads — invoices, tunes, shop notes, photos — and answers from them, with the source attached. It summarises what's been done, flags what's undocumented, and gets the car ready to sell.

What suspension is on the car right now?When was the clutch last replaced, and by whom?Which shop did the turbo install?What changed between v1 and v3 of the build?Is there documentation for the engine rebuild?Which receipts support the asking price?

When was the clutch replaced, and is there paperwork?
March 2023, at 74,900 km — twin-disc unit and lightweight flywheel, installed by the shop that also handled the fuel system. Two documents support it: the parts invoice and the shop's labour record, both uploaded by you in April 2023.

06The Loop
  1. 01Owner forwards receipts
  2. 02Car gets a structured file
  3. 03Every change is logged
  4. 04Buyer sees the whole build
  5. 05Cleaner record, stronger sale
  6. 06File transfers with the car
  7. 07Platform learns the patterns

Every logged car makes the system sharper on the next one. Every documented build sells for more than an undocumented twin. Every transfer hands the next owner the whole story instead of a stack of claims.

07From Content To Custody

They already post the build.
We keep the proof.

This culture documents everything visually and almost none of it structurally. The behaviour already exists — filming the teardown, posting the dyno pull, showing the respray. What's missing is a trusted place for the records underneath. Creators and community leaders don't advertise that behaviour; they set it.

08Resale

A documented build is an easier car to buy.

01

In modified cars, quality varies more than anywhere else in the market. Two cars with identical spec sheets can be a decade apart in build quality. Paperwork is the only thing that separates them before a test drive.

02

Claims are cheap. Receipts aren't. A file that shows who did the work, when, with which parts, converts a nervous buyer into a confident one — and confident buyers negotiate less.

03

The seller stops rebuilding the story from memory the week the listing goes up. It's been accumulating quietly for five years, and it goes out as one link.

The next owner should inherit the story, not just the keys.

09Shops & Builders

The work is already written down. It just never reaches the owner.

Performance shops, builders, restoration specialists, detailers and specialty dealers can push records straight into the car's file. Better handoff for the owner, a permanent credit line for the shop that did the work.

10Why Now
01

Enthusiast ownership went online and stayed there. Cars are bought, sold and judged through photos, threads and video — but the underlying paperwork never moved with it.

02

The modern enthusiast market is orders of magnitude larger than the concours world, and its cars change constantly. Constant change is exactly the problem a record system solves.

03

Models can now read a crumpled invoice, a shop note and a dyno sheet and turn them into structure. Two years ago this product was manual data entry. Today it's a forwarded email.

04

Distribution is the hard part in consumer, and it's the part we already have. An audience that builds, documents and trades cars is a distribution channel and a first cohort at the same time.

Every real build
deserves a real file.

These are crude thoughts from visiting your space at Aura today. With a mutual passion for cars, there may be more business here.
