Every private used car in the UK has a government MOT history — a detailed record of every test, every pass, every advisory. Bonafied benchmarks every private listing against that history. Only the top 15% earn a place on the platform. The best starting point for buying a used car privately in the UK.
Who it's for
The process
Here's exactly what happens before a listing reaches you.
We continuously monitor UK private seller listings across the open web — no dealers, no trade sellers. Ever. Every private car aged 8 years or older enters our screening pipeline automatically. That age threshold ensures every vehicle has at least five MOT tests on record — enough history to say something meaningful.
Every car in the UK must pass an annual MOT safety test once it reaches three years old. That record — every pass, every failure, every advisory notice going back years — is free, public government data. Almost nobody reads it systematically. We do. Using DVSA and DVLA data, we pull the full MOT history and score it against 20+ criteria: mileage consistency, structural corrosion, recurring faults, emissions issues, signs of neglect.
Just 1 in 6 listings makes the cut. The ones that do earn a badge. The ones that don't, you never see. We do the history work. You still need to see the car — but at least it's worth the drive.
Our standards
Every car on Bonafied earns one of two badges. Nothing makes it through without one.
A listing whose history doesn't just pass screening — it stands out within it. Clean pass record throughout, mileage that tells a consistent story, advisories that are minor and resolved. Evidence of genuine care, not just maintenance.
Credible history, consistent mileage, no red flags, no patterns of neglect. Advisories may be present — this is an 8+ year old car and advisories are normal — but nothing recurring, nothing structural, nothing that gave us pause. Worth your time. Worth a look.
Every listing on Bonafied — regardless of tier — is screened against a baseline that excludes write-offs, clocking indicators, structural corrosion, DPF issues and dealer listings. These are platform-wide standards, not tier distinctions.
The name
Like ratified, verified, qualified — words for things that have been properly looked at and found to stand up. Bonafied: a listing whose history earned its place. The spelling is deliberate.
"The best value in the private used car market. Found for you."
Over 3 million cars aged 8 years or older changed hands in the UK in 2025. Most were bought and sold on Facebook Marketplace, Gumtree and eBay — platforms with no benchmarking, no scoring, no independent quality signal. Dealers vet their stock before it reaches a forecourt. Private classified listings, historically, come with no equivalent standard. Until now.
Bonafied is the middle ground — private seller prices, with independent scrutiny most private buyers never get. We don't inspect cars. We don't sell cars. We benchmark every private listing against our scoring model and surface only the ones that clear it — so buyers have a credible, data-backed starting point before they pick up the phone.
The data is all there — free, public, government-held. We just apply the rigour that most buyers don't have time to apply themselves. A Bonafied listing means the MOT history checked out against our benchmark. It doesn't mean the car is perfect — inspect it properly before you buy. But it does mean the history gave us reason to put it in front of you. That's the point of this.
Join the list
We're building the shortlist we'd use ourselves. When Bonafied launches, list members get first look at every listing that makes the cut. No spam. No nonsense. Just the cars.
Just the launch. Nothing else.
