Gumtree is the easiest place in the country to check a car advert properly, and almost nobody does it, because the site's own safety advice never suggests it.
Here's the check that takes about ten seconds, and everything it does and doesn't tell you.
Is it safe to buy a car on Gumtree?
It's as safe as any private sale, which means the checking is entirely on you. Gumtree is a classifieds site: it doesn't inspect the cars, verify the sellers, hold your money or run any background check on a vehicle before it's listed.
That's not a criticism, it's just what a classifieds site is. It does mean Gumtree sits at the opposite end of the scale from somewhere like AutoTrader, which screens every listing before it goes up. On Gumtree nothing has been checked before you arrive, so everything you learn about the car, you have to go and find.
What Gumtree's own safety advice leaves out
A vehicle history check. Their car buying and selling safety guide covers spotting fake profiles, insisting on seeing the vehicle, checking the documents and the common scams, and as of September 2026 it doesn't mention checking the car's history anywhere.
That's a strange omission, because the most useful check available on a used car is free, official, and takes under a minute. The MOT history for any UK vehicle is published by the DVSA and it holds every mileage reading, every failure and every advisory the car has ever collected. Nothing in the advice you're given on the platform points you at it.
So the gap isn't that Gumtree is dangerous. It's that the guidance stops at "don't get conned by a person" and never reaches "here's how to find out about the car".
What is the advert not telling you?
Paste the advert text and the registration. We read it against the car's DVSA MOT history and our known-faults database, then tell you what the seller left out.

Copy the advert's web address and paste it in. That's the whole method, and Gumtree is the one big UK car platform where it genuinely works start to finish.
Tap the share icon on the listing, or copy the URL out of your browser's address bar, and paste it into the free scan. It reads the advert text, the asking price, the mileage and the year straight off the page, and picks up the registration if the seller has written one in. Then it pulls the official MOT history for that registration and reads the two against each other.
This is worth spelling out because it's the exception rather than the rule. Facebook Marketplace sits behind a login wall and AutoTrader blocks automated readers, so on both of those you have to screenshot the advert or copy its text out by hand. Gumtree doesn't block any of that, so the link on its own is enough.
Which Gumtree link should you paste?
The one for the single advert, not the page of search results you found it on. A Gumtree advert
address has the shape gumtree.com/p/<make>/<description>/<number>, ending in a long string of
digits.
It's an easy mistake because the two look similar on a phone, and it's the commonest reason a paste comes back with nothing useful. A search page, a category page or a location page contains dozens of cars and no single vehicle to read, so there's nothing there to check. If you paste one of those into our scan it'll tell you that specifically, rather than leaving you to wonder whether the link was broken.
If you're unsure, open the link fresh in a new tab. If it shows you one car with one price and one seller, it's the right address.
What if the advert doesn't show a registration?
Ask the seller for it before you arrange a viewing, and look for the number plate in the photos while you wait.
Plenty of private adverts don't include a registration anywhere in the text, and without one there's no official record to look up, because every record in this country is filed against the plate rather than against the advert. A private seller with nothing to hide hands it over without fuss: the plate is on public display every time the car is parked on the street.
The photos are the other route. Sellers who don't type the registration usually still photograph the car from the front or the back, so the plate is sitting in the picture. Zoom into the sharpest shot, then check what it returns against the advert before you trust it. O and 0, and I and 1, are indistinguishable on a compressed phone photo, and one wrong character pulls up a real but completely different car. If the DVLA vehicle enquiry service comes back with a different make, colour or year from the one in the advert, you've misread it.
A seller who has an answer for everything except the registration has told you something. "I'll give you it when you get here" means driving across the county before you're allowed to know anything about the car.
What should you check once you've got the registration?
Three official records, all free.
| Check | Where | What it gives you |
|---|---|---|
| MOT history | gov.uk | Every test, every mileage reading, every failure and advisory |
| Vehicle enquiry | gov.uk | Tax status, MOT expiry, engine size, colour, first registration date |
| Recall check | gov.uk | Outstanding safety recalls, which a franchised dealer fixes free |
The MOT history is the one that earns its keep, and it rewards reading properly rather than glancing at the latest result. Write the mileage readings out oldest first and look at the gaps between them. The shape that catches most clocked cars isn't a reading that goes backwards, it's years of heavy mileage that suddenly flatten just before the car was advertised, and how to spot a clocked car walks through the rest of them. Advisories matter too: the same item mentioned three years running is a job nobody has done.
It's worth knowing the specific car's weak points before you drive anywhere, because an advisory reads differently on a model with a known problem in that area. We keep a page per model, and the ones that turn up most on cheap private listings are a fair place to start: Vauxhall Astra known faults, Renault Clio known faults and Ford Fiesta known faults.
None of those three records covers outstanding finance, theft markers or write-off history. Those sit in licensed commercial databases, so no free service has them, and they matter more on a private sale than anywhere else. Outstanding finance on a used car sets out where you'd stand if money is still owing, which is better news than most people expect when you've bought privately and in good faith.
Does this work on eBay and Motors too?
Yes. Pasting the advert link works on eBay, Motors and Cars & Classic as well, for the same reason it works on Gumtree: none of them block an automated reader from seeing a public advert.
The same rule about which link to use applies. An eBay item address contains /itm/ followed by
the item number, so that's the one to copy rather than a search or category page.
The platforms where link pasting can't work are Facebook Marketplace and AutoTrader, and it's worth knowing why, because it isn't a limitation of any particular tool. Marketplace requires a login to see a listing at all, and AutoTrader challenges automated readers at the door. For those two the method is different rather than unavailable, and the Facebook Marketplace guide and the AutoTrader guide each cover their own.
Which of these gaps can a check actually close?
Take the concession first, because it's the thing most comparison pages dodge: on official records our data is the same data everyone else sells. Finance, theft markers and write-off records come from the lenders, the police and the insurance industry, and every provider draws on those same registers. Nobody holds a private source, us included.
The difference is what happens to the answer. A standard check hands you a page of facts and leaves you to work out what they add up to. Four former keepers, a corrosion advisory mentioned two years running and an advert that says "any inspection welcome, first to see will buy" are three ordinary facts apart and a fairly specific story together. Doing that reading is the job, and a list of records can't do it.
Three inputs a provenance check never takes:
- The advert text. Nobody files an advert against a registration, so no check has ever seen one. On a private Gumtree sale it's also the only thing in front of you that the seller wrote themselves.
- The full DVSA advisory history, read as a sequence rather than a list, so an item that keeps reappearing is treated as a job nobody has done.
- A known-faults database covering 41 makes, with 228 documented faults and 616 advert phrases that tend to show up alongside them.
On Gumtree specifically the free scan needs one thing from you, which is the link. Paste it and you get a verdict that takes the advert and the MOT history together, which is the check Gumtree's own safety guidance never mentions, and you get it without an account or a card.
If something turns up that needs the paid records, a Provenance Check adds the finance, theft and write-off lookups and scores them in rather than listing them at the bottom. A free report upgrades on the same link with nothing to re-run, so there's no decision to make up front. And if you want more on where free checks stop generally, what free car checks get you covers the whole line.
For the advert wording itself, private sellers give themselves away in how they phrase things far more than in what they actually disclose, and advert phrases that should worry you has the specific ones.
What none of this can tell you
Unrecorded accident damage. The quality of any repair. Whether the clutch is nearly gone. Whether rot you can't see in a photograph is cosmetic or structural.
None of it is in any database at any price, ours included, because nobody ever filed it. Every check on the market is a search of records other people created, and a car crashed and repaired without an insurance claim leaves nothing behind for anyone to find.
So use the checks for what they're genuinely good at, which is deciding which cars are worth driving to see. Then go and look at the one that survives, take someone who knows engines if you can, and remember that on a private sale the car is yours the moment you hand the money over.
