The Listing Says Private Sale — But Is It Really? How to Spot a Disguised Trader in 2025

Thousands of buyers hand over money each year to someone they think is a private seller, when legally that person is a trader. That distinction costs them everything when something goes wrong.

With 7.8 million used cars sold in the UK in 2025 and Motor Ombudsman complaints up 14% to 18,570 cases that same year, this is not a rare edge case. It is happening at scale, on AutoTrader, Facebook Marketplace, and Gumtree, right now.

What actually changes when you buy privately

When you buy from a dealer, the Consumer Rights Act 2015 applies in full. The car must be of satisfactory quality, fit for purpose, and as described. In the first 30 days you have the right to reject it outright for a full refund. After that, the dealer gets one chance to repair or replace before your final right to reject kicks in. "Sold as seen" signs are legally void when a trader puts them up.

When you buy from a genuine private seller, none of that applies. The sale is governed by the Sale of Goods Act 1979, on a straightforward caveat emptor basis. Your only real protection is that the car must match its description and be free of active misrepresentation. If the seller genuinely did not know about a fault and said nothing false, you have no statutory right to a refund, repair, or replacement.

What is a disguised trader?

A disguised trader is someone selling vehicles commercially while presenting themselves as a private individual to strip buyers of their legal rights. Trading Standards call it a banned practice. In some jurisdictions it is called curbstoning.

These sellers do not look like dealers. They list one car at a time, use first-person language, and give you a backstory: "upgrading to an SUV," "partner bought a new car," "no longer need it." But behind that single listing there is often a pattern: multiple sales in quick succession, cars bought at auction and flipped, no genuine connection to the vehicle's history.

One Principal Trading Standards Officer put the motive plainly: disguising a commercial operation as a private sale is done "to attempt to avoid legal responsibilities and liabilities, and in some cases to go further, for example to pass off clocked, unreliable and potentially unsafe vehicles to unsuspecting buyers."

What does the April 2025 law change mean for buyers?

The Digital Markets, Competition and Consumers Act 2024 came into force on 6 April 2025. It replaced the Consumer Protection from Unfair Trading Regulations 2008 and is the most significant overhaul of consumer protection law in over a decade.

Schedule 20 lists 32 commercial practices banned in all circumstances. Paragraph 25 explicitly prohibits: "Falsely claiming or creating the false impression that the trader is not acting for purposes relating to the trader's business or falsely representing oneself as a consumer."

In plain English: a trader pretending to be a private seller is now breaking the law under a specific, named prohibition. Twenty-nine of the 32 banned practices carry criminal liability. The Competition and Markets Authority also gained direct enforcement powers, including the ability to fine businesses up to 10% of global turnover without going to court. Most buyer-facing guides online predate this change entirely.

How many cars can a private seller legally sell?

There is no fixed statutory number. UK law does not say "sell more than six cars and you need a licence." What the law looks at is intent and pattern. A person is considered a trader if they buy cars mainly to resell at a profit, regardless of volume. Selling even one car with that intent could make you a trader in law.

In practice, Trading Standards and courts use volume as evidence of intent. Selling three to six cars per year, particularly with a clear pattern of buying low and selling higher, is the range where professional scrutiny kicks in. Sell eight cars in six months with no plausible personal reason for each, and you are almost certainly operating as an unlicensed trader.

This matters because if a buyer can demonstrate the seller crossed that line, Consumer Rights Act protections can apply retroactively. That changes a dead-end private sale dispute into a winnable legal claim.

One buyer purchased a Golf through what appeared to be a private listing, meeting the seller in a Tesco car park. Three weeks later, a serious clutch fault developed. He searched the seller's phone number and found eight cars listed over the previous six months from the same contact details. He took the case to small claims court on the basis that the seller was an unlicensed trader, and won £1,400.

7 red flags that expose a disguised trader

Before you view any car listed as private, check for these:

1. Multiple listings from the same number or address. Search the seller's phone number on Google. If other AutoTrader or Facebook Marketplace listings appear, that is a strong indicator of a trading pattern.

2. The meeting point is a car park, not a home. A genuine private seller has a home address linked to the vehicle. Reluctance to meet at the address on the V5C is a red flag.

3. Finance is offered. Private individuals cannot arrange motor finance. If a "private" seller mentions finance options, this alone is near-conclusive evidence of trader status.

4. Professional-quality photos. Phone snaps on a driveway are normal. Crisp, edited images with consistent lighting across multiple angles suggest someone who does this regularly.

5. The ownership story does not match the history. If the seller claims two years of ownership but the V5C shows the car was registered to someone else until eight months ago, that gap needs explaining.

6. Very recent keeper change. A car that changed hands six weeks before listing, with no service history from the new "owner," does not belong to someone who bought it for personal use.

7. Vague answers about where the car came from. Traders who buy at auction often cannot tell you where the previous keeper lived, what garage serviced it, or why the history stops abruptly. Genuine private sellers usually can.

What to do if you have already bought

If something has gone wrong after purchase, speed matters.

Screenshot everything first: the original listing, any other listings linked to the same number, the seller's profile page. Platforms delete listings quickly. Then search the seller's name, phone number, and address. Check Companies House for any business registration at that address. Look for other active listings on AutoTrader, Gumtree, and eBay Motors. If you find a pattern, document it with dates and prices.

Request a full MOT history through the DVSA's free checker and cross-reference the keeper timeline. A car with four registered keepers in 18 months, each holding it for only weeks, tells its own story.

If you can establish trader status, send a written rejection letter citing the Consumer Rights Act 2015 and the DMCC Act 2024 Schedule 20 prohibition on disguised trading. If the seller refuses to engage, small claims court covers disputes up to £10,000 in England and Wales, and the Golf buyer's case shows it can work.

Check the history before you meet anyone

The most useful thing you can do before viewing any private listing is run a vehicle history check. The keeper timeline, number of previous owners, and mileage records are all visible before you exchange a single message with the seller.

A car with four keepers in 18 months and a mileage record that does not match the seller's stated ownership period raises questions worth asking before you drive across the county to view it. A CarSense check surfaces exactly that kind of detail, so you can interrogate the seller's story from a position of knowledge rather than guesswork.

The listing says private sale. The price looks fair. The photos are decent. But the keeper history shows five owners in two years and the current keeper has held it for six weeks. That is not someone upgrading their car. That is someone running a business.
