Used comparison · 2025 DVSA data

Ford Mondeo vs Vauxhall Insignia

The two big British fleet saloons, now cheap used and often very high mileage.

Across 351,367 initial MOT tests in 2025, the Vauxhall Insignia passed 73.17% against 73.09% for the Ford Mondeo. That is close enough that the specific car matters far more than the badge.

Head to head on the MOT record

The UK average across all cars in this data is 77.3%. The Ford Mondeo sits below it by 4.2 points, and the Vauxhall Insignia sits below it by 4.1 points. The Ford Mondeo also arrives at test with roughly 12,488 more miles on average, which usually says more about who buys it and what they use it for than about how long it lasts.

Which one holds up better as it ages

This is the part that matters when you are buying used. A headline pass rate mixes three-year-old cars in with fifteen-year-old ones. Split by age, you can see what each model actually does over time.

The Vauxhall Insignia gives up less as it gets older. Between the youngest and oldest brackets it loses 18.2 percentage points against 21.4 for the Ford Mondeo, a difference of 3.2 points. On a ten-year-old example that is the figure to weigh, not the headline number.

What each one fails on

These are the areas testers recorded most often across every failed 2025 test for each model. Read them as a viewing checklist for that model, not as a fault list for any particular car.

Both models fail most often on suspension, which is normal for cars of this age and tells you what to look at on either. The difference between them is in what comes next on each list.

The specific items testers wrote down

One level deeper than the category. These are the individual defects recorded most often on each model.

What this comparison cannot tell you

Everything above describes two models across the whole UK fleet. It says nothing about the one car in the advert you are looking at. Two Mondeos of the same year and mileage can be worth thousands apart because of things that never appear in MOT data:

• Outstanding finance. If a lender still has an agreement recorded against the car, that claim does not disappear because you paid the seller.
• Insurance write-off history. A Cat S or Cat N marker is permanent, changes what the car is worth, and does not appear on the V5C.
• Stolen markers. A car recorded as stolen can be seized even from a buyer who bought it honestly.
• Mileage history. The readings taken at every MOT are the clearest way to spot a clocked odometer.
• Previous keepers. An unusual number of keepers for the age of the car is worth asking about.

A Carpeep car history check reports all of those against the registration, plus tax status, import and export markers, scrapped status and the recorded vehicle identity, in one £15 report.

Ford Mondeo vs Vauxhall Insignia FAQs

Is the Ford Mondeo or the Vauxhall Insignia more likely to pass its MOT?

The Vauxhall Insignia passed 73.17% of its initial MOT tests in the DVSA 2025 data against 73.09% for the Ford Mondeo, a gap of 0.1 percentage points. That is a fleet-wide average, not a prediction about the specific car you are looking at.

Does a higher MOT pass rate mean a more reliable car?

No. An MOT records whether a vehicle met the roadworthiness standard on the day it was tested. It does not test the engine, clutch or gearbox, and it does not measure how often a car breaks down. Pass rates are useful for comparing how two models are holding up across the whole UK fleet, and nothing more than that.

Which is cheaper to keep on the road, the Ford Mondeo or the Vauxhall Insignia?

This data does not price servicing or repairs, so it cannot answer that directly. What it does show is what each model most often fails on, which is a fair guide to where the money goes. The Ford Mondeo fails most often on suspension. The Vauxhall Insignia fails most often on suspension.

How do I check the actual Vauxhall Insignia I have found?

Enter its registration. A Carpeep car history check reports outstanding finance, insurance write-off markers, stolen markers, the mileage recorded at every MOT, previous keepers, tax and MOT status, import and export markers and scrapped status in one £15 report. None of that appears in model-level MOT statistics.

Which one has covered more miles by MOT time?

The average Ford Mondeo arrived at its 2025 MOT on 116,504 miles, against 104,016 for the Vauxhall Insignia. That usually reflects who buys each car and what they use it for rather than how long it will last.
