The 5-minute check that could save you £4,800 on a used car
CarVertical lets buyers check and compare vehicle histories to rule out problem cars and make the right call
That gleaming Audi in the listing looks perfect. One careful owner, full service history, priced to sell. You're already picturing yourself behind the wheel.
But here's what the photos won't show you: whether it was written off in a motorway pile-up two years ago. Whether someone's wound back 35,000 miles. Whether there's £8,000 of outstanding finance attached to it.
These aren't edge cases. According to data from carVertical, a vehicle history service that pulls records from over 900 international databases, 17% of UK vehicles have at least one damage record. That's roughly one in five cars. And when damage has been repaired on the cheap? Even mechanics could miss the signs.
A history check won't tell you everything, but it flags problems you'd never spot in person. Here's what to look for and how to use the information.
What a vehicle history check actually tells you
Accident and damage records. Not just whether a car was damaged, but photos, repair costs, and severity. The average repair cost for a single damage record sits at £4,800. For premium cars, that figure climbs into tens of thousands.
Why does this matter? A cosmetically sound repair can completely mask a compromised structure. The car looks fine, drives fine on a test run, and even a busy mechanic might not catch subtle signs like minor paint misalignment or a small trim issue. But cheap repairs using low-quality parts tend to fail sooner, leading to unexpected costs down the line. Worse, a badly repaired car can have serious safety problems: missing airbags, weakened crumple zones, or components that won't perform as designed in another collision.
Mileage verification. Clocking is alive and well. 2.3% of UK vehicles checked by carVertical had rolled-back odometers, by an average of 35,000 miles. Some models are worse: nearly 1 in 10 used Nissan Qashqais have tampered mileage.
The problem isn't just overpaying (though you will). A car's price is closely tied to mileage, so a rolled-back odometer inflates the value immediately. But the real issue is what comes next. Mileage determines when parts need replacing: timing belts, brake pads, clutches, suspension components. If the odometer says 60,000 miles but the car has actually done 95,000, you're driving a vehicle that's overdue for maintenance you don't know it needs. That timing belt failure at 70,000 miles? It was supposed to be changed at 60,000.
Theft and finance flags. Buy a car with outstanding finance and the lender can legally repossess it. Buy a stolen one and you lose both the car and your money.
Service and ownership history. Gaps in servicing or a long list of previous owners tell you plenty about how a car's been treated.
Comparing multiple cars? The carVertical Score helps
If you're weighing up several options, checking each report in detail gets tedious. The carVertical Score simplifies this: it's a 0-100 rating that summarises the car's history into a single number. A score of 86-100 means a clean history, while anything below 60 signals serious issues worth investigating.
The score is calculated from three categories: operation (mileage, age, ownership changes), defects (damage, failed inspections, recalls), and dispossession (theft, finance restrictions). It's not a replacement for reading the full report, but it lets you quickly compare cars and filter out the ones that aren't worth your time.
How to actually use a report
A history check isn't a replacement for an inspection. It's what makes the inspection worthwhile.
Pull the report before you visit. If it shows previous damage, you can ask the seller directly and watch their reaction. If they didn't disclose it, that tells you something. If they did, you now know exactly what to ask a mechanic to look at.
It also gives you leverage. A car with a hidden past is worth less than the asking price, and a report gives you the evidence to negotiate.
The bottom line
Five minutes and a registration number or VIN. That's all it takes to avoid overpaying for a car that's been crashed, clocked, or stolen.
