Same parts-bin, different MOT result
The Skoda Fabia and Volkswagen Polo are close enough in layout, engines, ownership profile and group engineering that the cheap answer would be: buy the cleaner individual car. That is still true. But the 2024 public UK MOT record gives the Fabia the cleaner headline. It passed first time at
Pass-rate split
The Fabia recorded 395,184 MOT tests in the 2024 model record. The Polo recorded
The headline gap is simple:
There is a fair objection here. The Polo sample is nearly three times larger, and it reaches further back into the older UK car park. The Polo first-use range in this record runs back to 1977, while the Fabia record starts in 2000. That gives the Polo more very old survivors, more edge-case cars, and more opportunity for cheap, tired examples to drag the average down.
But that is not enough to wave away the result. Most used buyers are not cross-shopping a 1970s Polo against a Fabia. They are looking at small hatchbacks from the last 10 to 15 years, and the cohort split still favours Skoda in the two bands that carry most of the useful buying weight.
Where they fail
The two cars share much of the same small-front-drive reality: suspension wear, CV boots, tyres, lamps, wipers and screen damage. The badge changes the showroom conversation more than the MOT failure menu.
The Fabia’s top recorded failure reasons are:
- Suspension pin, bush or joint excessively worn: 11,448
- Transmission shaft constant velocity joint boot severely deteriorated: 10,378
- Rear registration plate lamp or light source missing or inoperative: 8,289
- Windscreen or window damaged or seriously discoloured, without badly affecting the driver’s view: 7,722
- Tyre tread depth below requirements: 6,897
The Polo’s top recorded failure reasons are:
- Rear registration plate lamp or light source missing or inoperative: 40,099
- Steering rack gaiter or ball joint dust cover damaged or deteriorated: 36,979
- Transmission shaft constant velocity joint boot severely deteriorated: 27,533
- Suspension pin, bush or joint excessively worn: 27,163
- Windscreen or window damaged or seriously discoloured, without badly affecting the driver’s view: 22,760
That Polo steering-rack gaiter and dust-cover signal matters. It is not an exotic failure. It is the kind of rubber-and-road-grime issue that tells you how the car has lived and how often anyone has been underneath it with a torch before test day. On the Fabia, the leading items are more evenly spread across suspension joints, CV boots, number-plate lighting, glass and tyres.
The practical buying lesson is blunt. Do not be hypnotised by a small hatchback that feels tight on a short test drive. Put it on full lock both ways. Listen for front-end knocks. Look for grease around CV boots. Check tyre shoulders. Look at the rear plate lamps before you even open the driver’s door. These cars often fail on things a careful owner could have spotted in five minutes.
Cohort tells
The age-band split is where this comparison stops being a badge argument.
Pre-2018 cars dominate both records. The Fabia has 328,322 tests in that band and passes first time at 73.37%. The Polo has 972,985 tests and passes at 71.5%. That is a 1.87-point Skoda lead in the band most used buyers will actually meet at cheaper money.
The 2018-2020 band is tighter. The Fabia records 53,870 tests and passes at 85.91%. The Polo records 147,278 tests and passes at 85.1%. Again, the Fabia is ahead, this time by 0.81 points. That is not a dramatic split, but it matters because these are exactly the cars buyers often see as the sweet spot: modern enough, not new-car money, old enough for real maintenance patterns to show.
The 2021-on band flips the result. The Fabia records 12,992 tests and passes at 87.28%. The Polo records 13,462 tests and passes at 90.02%. For younger cars, the Polo looks cleaner.
That does not overturn the verdict, because the 2021-on samples are much smaller and younger cars are still in the easy part of their MOT life. A three- or four-year-old small hatch should be passing unless it has been kerbed, ignored, poorly repaired or run on dead tyres. The more revealing question is what happens once the car has lived through winter salt, budget tyres, school runs, missed servicing and cheap repairs.
On that measure, the Fabia has the better story. It leads in the older cohort, and it leads in the middle cohort. Those are the cars where ownership quality and durability begin to separate.
The Polo looks better when young. The Fabia looks better when the car has had time to become a used car.
That is the key split. If you are buying nearly new, the Polo’s younger-cohort result helps it. If you are buying the normal used-market car, the Fabia’s older and middle bands are more useful.
Mileage tells
Average mileage at test adds another useful check. The Fabia’s average mileage at test is 72,790 miles. The Polo’s is 71,098 miles. The Fabia is carrying 1,692 more miles on average while still posting the higher first-time pass rate.
That is a small but meaningful nudge. A car that passes more often while arriving with slightly more mileage is doing something right, or attracting owners who keep it in better test shape, or both. The public record cannot separate engineering durability from owner behaviour perfectly. It can show the result of both turning up at the test station.
The fuel mix is also worth keeping in mind. The Fabia record is mostly petrol, with 308,543 petrol tests and 86,617 diesel tests. The Polo is even more petrol-heavy: 1,034,509 petrol tests and 99,161 diesel tests. This is not a diesel-workhorse comparison. It is mostly a small petrol hatchback comparison, with some older diesel presence in the background.
Mileage also changes how you should inspect each car. On a Fabia around 80,000 miles, pay attention to suspension bushes, CV boots, rear plate lamps, tyres, wipers and screen damage. On a Polo at similar mileage, add a particularly careful look at steering rack gaiters and ball joint dust covers. None of this is glamorous. That is why it matters. MOT failures are often boring before they are expensive.
The Ford Fiesta is the useful third reference point here because it sits in the same UK small-car pool. If the Fabia and Polo both look tired, do not force the VW Group choice. A clean Fiesta with better history can beat both. The data gives you a starting bias, not permission to ignore the individual car.
The numbers we trust
This comparison uses the 2024 public UK MOT record behind the model pages for the Skoda Fabia and Volkswagen Polo. The useful top-line numbers are:
- Skoda Fabia: 395,184 tests, 298,517 passes, 75.54% first-time pass rate, 72,790 average mileage at test
- Volkswagen Polo: 1,133,725 tests, 833,123 passes, 73.49% first-time pass rate, 71,098 average mileage at test
- Headline gap: Fabia ahead by 2.05 percentage points
- Pre-2018 pass rate: Fabia 73.37%, Polo 71.5%
- 2018-2020 pass rate: Fabia 85.91%, Polo 85.1%
- 2021-on pass rate: Fabia 87.28%, Polo 90.02%
The biggest limitation is age mix. The Polo has a much larger and older long-tail fleet, and that can drag down the headline pass rate. That is why the cohort section matters more than the badge. When the record is split into first-use bands, the Fabia still leads in pre-2018 and 2018-2020 cars. The Polo only takes the younger 2021-on band.
The second limitation is maintenance behaviour. MOT records measure the car as presented for test. They do not tell you whether a careful owner replaced tyres the week before, whether a cheap owner ignored a knocking joint for six months, or whether a car was repaired properly after a previous fail. That is not a flaw in the numbers. It is how used cars work.
For buyers, the verdict is practical. Start with the Fabia if the cars are similar. It has the higher pass rate, the stronger older-car split and slightly higher average mileage at test. Then let condition overrule the spreadsheet. A Polo with clean history, recent tyres, intact boots and a tidy underside is a better buy than a Fabia with cheap rubber, misted lamps and old advisories repeating year after year.
The right way to use this comparison is to read the individual MOT history before viewing the car. Repeated advisories are more revealing than one-off fails. A car that keeps warning on tyres, suspension play or dust covers is not being maintained ahead of the test. A car with old failures repaired properly and no repeat pattern is often less scary than a car with a clean-looking advert and a lazy advisory trail.
The Polo is not a bad small car, and younger Polos look stronger in the 2021-on cohort. But as a used-buy default, the Fabia is the sharper MOT-data pick. Pay Polo money only when the individual car has cleaner history, better tyres, intact boots and fewer signs of neglected front-end wear.
