A tool with one job.

Help UK Copart buyers decide before they bid. Nothing else.

Last updated

CarMargin started from a simple frustration: every Copart UK listing has roughly the same set of questions a serious buyer needs answered, and answering them properly takes thirty minutes per lot. Multiply by a watchlist of ten and an evening disappears before any bidding happens.

The questions are mostly the same. What's the actual damage, beyond the headline category. Does the MOT history confirm the displayed mileage. What does the repair plausibly cost. What's the resale haircut going to look like. What can't be seen from the photos that should worry you.

CarMargin runs that work for every lot you open. The output is one page of analysis, a recommended max bid tuned to your settings, and a chat that will dig deeper into anything specific. The aim is not to bid for you. It's to give you, in a minute, what would otherwise take half an hour.

Four rules.

01

Specific beats general.

A tool that does one thing well for one country is worth more than a tool that does ten for everyone. UK Copart only, until UK Copart works perfectly.

02

Cite the source.

AI analysis is only useful if you can verify it. Every claim points back to the photo, listing field, MOT advisory, or analysis section it came from.

03

Be specifically uncertain.

Photo-based AI cannot see engine compression. The MOT record cannot tell you whether the dashboard cluster has been swapped. CarMargin lists what it can't see as plainly as what it can.

04

Privacy by architecture.

Photos pass through and are discarded. VRNs aren't linked to user accounts. The cache isn't queryable. Bidding history stays between you and Copart. See the privacy policy for the architecture.

What we're not.

  • A marketplace.
  • A Copart competitor.
  • A bidding bot.
  • A vehicle history database.
  • Affiliated with Copart in any way.
