The Most Misleading Used Car Ads of 2025 - Trends and Tactics

Why Misleading Ads Became So Common in 2025

The year brought big changes. Many sellers were dealing with higher repair costs, slower sales, and lower valuations. That meant some stretched the truth to make their listings more appealing.

Three big pressures drove misleading wording:

• rising competition between private sellers and dealers

• slow moving models that needed dramatic adverts

• buyers becoming more cautious and harder to convince

Instead of improving the cars, many sellers simply improved the description.

The Misleading Tactics That Defined 2025

These were the biggest ad patterns flagged by buyers and exposed through car history checks.

1 - The Overly Confident Mechanical Claim

This was one of the most common lines in 2025:

"Drives like new"
"Perfect engine"
"Faultless drive"

Buyers quickly learned that these claims rarely matched reality. In fact, many of the cars described this way had:

• recent MOT failures

• long lists of advisories

• engine warning light resets

• oil leaks

• timing chain noise

• poor emissions history

A quick look at the car’s history on TopCarCheck often told a different story. Clean wording didn’t equal a clean engine.

2 - The History That Was Technically True But Completely Misleading

Many sellers claimed things like:

"Full history"
"Well maintained"
"Long history"

But when checked properly, this often meant:

• 2 stamps in 10 years

• partial history from a single garage

• no record of major servicing

• gaps of 40,000 miles or more

• missing invoices for expensive work

In 2025, buyers became more sceptical of history claims. They relied on MOT patterns, mileage changes, and keeper history instead of the seller’s description.

3 - The Strategic Use of Vague Mechanical Descriptions

Thousands of ads in 2025 used vague but positive sounding phrases. A few examples:

• "Recently checked"

• "Mechanically sound for its age"

• "Starts and stops as it should"

• "No obvious issues"

• "Feels solid"

These phrases appeared most often in ads where the seller knew the car needed:

• suspension work

• brake replacement

• gearbox attention

• new tyres

• emissions repairs

Vague wording created false confidence without providing real information.

4 - The Mileage Distraction Trick

Some ads highlighted mileage in a way that made the car appear cleaner than it was.

Examples:

"Low mileage for the year"
"Decent mileage"
"Below average mileage"

But many of these cars had:

• inconsistent mileage readings

• clusters swapped in previous ownership

• MOT mileage drops

• mileage rollbacks after import

• high idle hours despite low miles

2025 saw a noticeable spike in mileage inconsistencies flagged by TopCarCheck. Buyers knew this was one of the most misleading claims of the year.

5 - The Photos That Hid More Than They Showed

Another huge trend in 2025 was selective photography. Sellers posted:

• dark photos

• cropped edges

• no close ups

• no interior photos

• no bonnet shots

• no tyre photos

• no dashboard warning light images

These photos were often used to hide:

• body damage

• mismatching paint

• worn tyres

• missing trim

• dashboard faults

• smoking exhausts

• poor interior condition

Buyers began avoiding poorly photographed listings altogether.

6 - The Price That Looked Too Good To Be True

Underpriced cars were a major red flag in 2025. Most of them fell into one of these categories:

• outstanding finance

• previous write off

• imported and not declared

• category S or N with no mention

• serious mechanical faults

• stolen and recovered

Cheap cars got the highest number of checks on TopCarCheck, because buyers learned the pattern quickly. Low price meant high risk far too often.

7 - The Misleading MOT Comment

MOT results were often misrepresented in ads.

Common misleading claims:

• "Full year MOT" when it had 364 days

• "Clean MOT" when it had 5 advisories

• "No issues" when last year had major failures

• "Fresh MOT" after only minor work was done

Some sellers hoped buyers wouldn’t check the full MOT history. But in 2025, more buyers checked than ever before.

8 - The Undeclared Write Off

The biggest red flag of 2025.

Many ads had:

"No issues"
"Great condition"
"Nothing to worry about"

But once checked, the car came back with:

• category S

• category N

• significant structural repairs

• welded panels

• insurance claims

This became one of the most common forms of misleading advertising in the UK used market.

The Most Common Words Used in Misleading Ads in 2025

Below is a breakdown of the phrases that appeared in thousands of questionable ads during the year.

The Sellers Who Used These Tactics Most

Misleading ads appeared across all platforms, but patterns showed the highest risk areas:

• Facebook Marketplace

• Gumtree

• Instagram listings

• small roadside dealers

• unregistered traders posing as private sellers

This didn’t mean all listings on these platforms were bad. But they had the largest number of reported misleading ads in 2025.

How Buyers Learned to Spot Misleading Ads Faster

The year also showed a huge shift in buyer behaviour. Instead of taking ads at face value, buyers began to:

• check MOT history first

• research common issues of the model

• compare price to market value

• look for keeper changes

• check previous number plate history

• run a full TopCarCheck report

• inspect photos for signs of repair

Buyers used history checks as the first step, not the last.

Real Warning Signs Buyers Noticed in 2025

These were the top red flags that made buyers walk away instantly:

• seller refuses to provide the reg

• car has been listed repeatedly

• price drops every few days

• no service history provided

• reg plate blurred out

• photos taken on different days

• ad language too pushy or urgent

• seller avoids phone calls

• no test drive allowed

• missing V5C details

Sellers who were honest usually had no problem sharing the full vehicle details. Sellers who refused were often hiding something.

The Models That Appeared Most Often in Questionable Ads

Based on thousands of checks, the models most frequently tied to misleading ads were:

• BMW 1 Series

• Audi A3

• Volkswagen Golf

• Mercedes A Class

• Ford Focus

• Vauxhall Corsa

• Nissan Qashqai

• Range Rover Evoque

These cars were popular, easy to sell, and easy to misrepresent. They also had repairs that could be hidden with basic cosmetics if buyers were not careful.

How History Checks Exposed the Truth Behind The Ads

In 2025, the biggest defence against misleading ads was accurate data.

A single vehicle report exposed:

• previous accident damage

• write off category

• mileage anomalies

• imported status

• stolen alerts

• plate changes

• keeper history inconsistencies

This information helped buyers avoid common traps.

Conclusion - 2025 Was The Year Buyers Learned To Read Between The Lines

They checked cars more carefully.
They questioned every promise.
They relied on history checks instead of seller wording.

By the end of the year, the UK used car market became a place where honesty mattered more, because most buyers were too well informed to fall for old tricks.

If you are buying in 2026, start the same way thousands of careful buyers did in 2025.
Run a full car history check before you view anything.
It helps you avoid the misleading ads that still appear every day.
