How CarBuilds works

Your car build, from the first bolt to the final handover.

One line runs through the whole thing: what you did, what went on the car, what it cost, and the record you hand over when you sell it.

01

Log your car build in seconds, with AI

Type one sentence or snap the receipt. CarBuilds writes the rest.

  • Receipts, the odometer and parts boxes become costs, mileage and part numbers
  • It picks the right car out of your garage
  • You review and edit everything before it is saved

02

Every mod, part and service in one car build log

One build log instead of receipts, DMs, forum posts and a spreadsheet.

  • Parts and mods with brands, part numbers and install dates
  • Oil changes with viscosity, filter and the next due mileage
  • Alerts for inspection, insurance and service dates

03

Know what your custom car build really cost

Every expense in your currency, against a budget you set.

  • Receipts and invoices attached to the expense they belong to
  • Spending by month and across every car in the garage
  • A market value estimate next to what you have put in

Your whole garage, and a car build history you can hand over

Every car in one place, and a record the next owner can trust.

  • Garage value and total spend across every build you own
  • A health score that shows what each build is still missing
  • A printable service record, a share link, and full transfer when you sell

Why CarBuilds

Built for people who document their car builds

Not a configurator — a place to record the build you already own

A verified build history

Every repair, mod, or tune-up you log becomes part of a trusted record — a transferable asset you can hand over when you sell the car.

01

You control what you share

Keep your builds private, share with followers, or publish publicly. You decide who sees what and when — from start to sale.

02

Made for the car build community

Built by and for car lovers. Whether you're restoring a classic or tuning a track car, carbuilds.com is your platform to document and connect.

Questions

What people ask before they start a build log

How the build log works, who gets to see it, and what happens to it when the car changes hands

What goes into a car build log?
Every change to the car, in the order it happened. An entry carries what you did, the parts that went on with their brand and part number, what it cost and who you bought it from, the odometer reading at the time, and the photos you took. An oil change also keeps the viscosity, the filter, the spec approval and the next service due by both date and mileage.
Can CarBuilds replace my car build spreadsheet?
That is what most people move across from. A spreadsheet cannot hold the workshop invoice, the photo of the part number or the receipt for the parts, and you cannot hand anyone a link to it. CarBuilds keeps the same running costs and adds the parts list, the gallery, the service history and a page for the whole build.
Can I see other custom car builds of the same model?
Yes. Public builds have their own page and are grouped by make and model, so you can read through other Audi S7, Golf GTI or Mustang projects before you commit to parts on yours. Follow a build and its new entries show up in your feed.
Who can see my build, and can I keep parts of it private?
You choose per build: private, friends only, followers only, or public. The sections are separate, so you can publish the timeline and the gallery while the expenses stay yours alone. Anyone you invite as a collaborator only gets the sections you hand them.
What happens to the car build history when I sell the car?
You transfer it to the buyer, so the car arrives with its own history instead of a folder of receipts. Before that you can give them a printable service record on a public link, listing the vehicle details, the parts fitted and what was paid for the work.
Can I prove the work and the money that went into the build?
Each expense keeps its receipt or invoice, each part its number and supplier, and each service its date and mileage. The totals run against a budget you set and sit next to a market value estimate for the car, so what you have put in and what it is worth are in the same place.
