Ford Fiesta vs MINI Cooper: which is the better used buy?

On DVSA MOT records the MINI Cooper does better at its MOT: measured against cars of the same age, it comes out 7.9 percentage points ahead of the Ford Fiesta on first-time MOT passes. That comparison covers 187,072 real tests across every generation on the road, not a survey. A pass with rectification at the station counts as a pass here, and as a failure in DVSA's own initial-test measure. The MOT checks safety and emissions items, not the engine, clutch or gearbox, so this is one measure of how each car holds up rather than a full reliability verdict; the common faults below cover the rest.

MOT first-time pass rate

Counted from DVSA’s anonymised MOT test records. “vs age-matched” compares each model against what the national fleet scores at the same age — the only fair better-or-worse number, because an older fleet fails more whatever its build quality.

These figures count every generation still on the road, not only the one described below: mostly Ford Fiestas registered 2001–2022 and MINI Coopers registered 2010–2022.

Source: DVSA MOT Anonymised Data 2025 (Open Government Licence v3.0). National first-time pass rate 77.3%. Class 4 tests in Great Britain, test type NT (a normal annual test), retests excluded. A pass, or a pass with rectification at the station, counts as a first-time pass; DVSA's own initial-test measure counts a rectified pass as a failure and so reports a lower figure. Testing in Northern Ireland is run separately by the DVA under its own rules. The difference is worked out before rounding, so it can be 0.1 away from the two rounded figures beside it.

Ford Fiesta

Mk8 (2017–2023) · A supermini / small hatchback and one of the UK's most common used cars, competing with the Vauxhall Corsa, VW Polo, SEAT Ibiza and Peugeot 208.

The Ford Fiesta Mk8 (2017–2023) is a generally dependable used supermini. The key check on a 1.0 EcoBoost is its timing system: early cars (launch into 2018/2019) have the original wet cam belt, which can shed debris and destroy the engine, while mild hybrids use a chain-driven camshaft. Confirm by engine code. Best buy: 2022–2023. Worst: 2017.

What goes wrong

  • Safety recall R/2025/084recall
    Puma Fiesta Courier – Fuel line chafing
    26,004 vehicles of this model (DVSA’s figures added up) · built between 22 December 2021 and 11 July 2023
    Large recall — 26,004 vehicles. Check a car by registration on GOV.UK.
  • Engine — 1.0 EcoBoost wet timing beltcritical
    Engine rattle or knocking noise, sudden loss of power, warning lights, or complete engine failure if the belt sheds material into the oil system and blocks oil galleries or the pickup strainer; metallic debris can also show up in the oil at a routine service.
    Broadly 2017 into 2018/2019: 1.0-litre EcoBoost non-hybrid Fiestas from this window most commonly have the original wet cam timing belt. Ford introduced a revised, chain-driven camshaft design during 2018–2019, which every 1.0 EcoBoost mild-hybrid (mHEV, 2020 on) version uses; these still have a separate, smaller wet belt driving the oil pump. The cut-over wasn't a clean model-year change, so confirm by engine code/VIN rather than assuming from year alone. Does not affect the naturally aspirated 1.1 Ti-VCT petrol. · For cars confirmed to have the original wet cam belt: Ford's original quoted interval was 10 years/150,000 miles (later tightened industry-wide to nearer 6 years/100,000 miles); independent specialists recommend replacement nearer 60,000–80,000 miles given how often belts have failed well inside those figures. · Roughly £600–£1,650 for a preventative belt replacement at an independent EcoBoost specialist (commonly £950–£1,200+VAT; significantly more at a main dealer); if the belt fails, a replacement or reconditioned engine typically runs £2,000–£4,000+, more in severe cases.
    Check: Confirm the engine variant by engine code or VIN check rather than assuming from registration year alone. For any car confirmed to have the original wet-belt engine, ask for a dated invoice proving wet-belt replacement (not just a general service stamp), and budget for the job immediately if there's no such record, regardless of the odometer reading. Even on revised chain-cam/mHEV cars, ask about the condition of the separate oil-pump belt.
  • Body sealing — door seals, boot and rear footwellsminor
    Damp carpets, a musty smell, water pooling in the boot floor or spare-wheel well, wet rear footwells, and — if left unresolved for a long time — electrical faults or corrosion from water sitting inside the car.
    2017–2023, reported across the generation · Not mileage-related; can appear on low-mileage cars if a seal, grommet or drain point has failed · Resealing a door seal, boot seal or roof-rail drain point is typically £50–£150 in parts and labour if caught early; ignoring it can lead to far costlier electrical or interior repairs
    Check: Lift the boot floor and spare-wheel cover and pull back the edges of the rear carpet to feel for damp or staining, sniff for a musty smell, and check the roof lining above the doors and around the rear pillars for water marks.
  • 1.5 TDCi diesel particulate filter (DPF)major
    Engine management light, limp mode or reduced power, poor fuel economy, black smoke under hard acceleration, and DPF-related MOT failures.
    2017–2023, 1.5 TDCi diesel variants only · Can occur well inside 60,000–80,000 miles on cars used mainly for short, low-speed journeys that never let the filter fully regenerate · A forced regeneration or DPF clean is roughly £100–£300; a full DPF replacement can run to £1,000–£1,500+
    Check: Ask how the car is normally driven (motorway runs vs. short urban trips), check the MOT history for DPF-related advisories or failures, and where possible take it on a drive long enough to let a regeneration complete during the test.

MINI Cooper

F56 (2014–2023) · Premium-badged three-door hatchback (the closely related 5-door F55 and Convertible F57 share the same platform and engines), sold new in the UK in Cooper, Cooper S, John Cooper Works and Cooper D/SD diesel guises, with a Cooper SE electric derivative added from 2020.

The third-generation MINI Cooper (F56), sold in the UK from 2014 to 2023, is a fundamentally reliable small hatchback once past its early teething problems. From around 60,000 miles, owners report timing-chain rattle on the 3-cylinder engine, water pump leaks and clutch wear. Diesels built up to October 2017 are covered by DVSA EGR-cooler recalls, and up to October 2018 by an EGR software recall. Best buy: 2019–2023. Worst: no single year stands out on DVSA MOT results.

What goes wrong

  • Safety recall R/2020/179recall

    Large recall — 71,128 vehicles. Check a car by registration on GOV.UK.
  • Safety recall R/2023/174recall
    On some diesel vehicles glycol leakage from the EGR-Cooler may occur. In very rare cases this could lead to the melting of the Intake manifold and in very rare cases result in a possible fire.

    Large recall — 30,812 vehicles. Check a car by registration on GOV.UK.
  • Crankshaft (bottom-end) bearing noise – early Cooper S petrol enginescritical
    Knocking or rattling noise from the lower engine/bell-housing area, an unusual or hard-to-depress clutch pedal action, and an illuminated engine management light; left unaddressed this can progress to bottom-end engine damage.
    2014 to early 2015 build dates (Cooper S petrol models) · Can appear at low mileage — not linked to high mileage · A bottom-end rebuild or engine replacement can run to several thousand pounds (roughly £2,500–£5,000+).
    Check: Listen for knocking on a cold start and check the clutch engages smoothly with no odd pedal feel. This is not a DVSA safety recall — DVSA lists no crankshaft-bearing recall for any MINI — so ask a MINI specialist to inspect rather than relying on a recall check.
  • Timing chain stretch – 3-cylinder B38 petrol engine (Cooper, One)major
    A metallic rattle or 'tak-tak' noise on cold start-up that fades as the engine warms; rough idle, misfires or a check-engine light if the chain has stretched significantly.
    Mainly pre-facelift cars, 2014–2017, on 3-cylinder Cooper/One models · Typically 60,000–80,000 miles, occasionally earlier · Upper timing chain and tensioner replacement at an independent BMW/MINI specialist typically £500–£900; main dealer pricing is higher.
    Check: Listen for a rattle from the front of the engine on your own cold start (not one the seller has already warmed up); check service history for any timing chain/tensioner inspection or replacement.
Typical asking price:
£4,999–£15,795, median £8,990 (middle 80% and median, cars on Autoza on 11 November 2026)

A car registered from April 2017 with a list price over £40,000 when new adds the £440/year Expensive Car Supplement in years 2–6 (£640 in all). Cars registered 2001–2017 pay a CO2 band, roughly £20–£790/year (2026/27 rates). Electric versions: one first registered from 1 April 2025 pays the £440/year supplement in years 2–6 only if it listed at over £50,000 new; one registered before then never does, whatever it cost.

Which one suits you

Ford Fiesta

Good for: First-time buyers and anyone prioritising low running costs — cheap parts, low insurance groups and a huge independent-garage network. The 2020+ mild-hybrid EcoBoost is the safer pick for the wet-belt risk.

Less good for: Buyers wanting maximum rear legroom or boot space — this is a genuinely small car. A pre-2019 1.0 EcoBoost with no documented wet-belt history, given how expensive getting that wrong can be.

MINI Cooper

Good for: Buyers wanting genuine go-kart-style handling and premium interior feel in a small car, and willing to pay MINI-dealer or specialist rates once out of warranty. A 2019+ car with a full main-dealer or MINI-specialist history is the safer buy.

Less good for: Anyone on a tight budget for servicing — parts and labour cost more than mainstream superminis. An early 2014–2015 car with patchy timing-chain and cooling-system history.

Frequently Asked Questions

Which is more reliable, the Ford Fiesta or the MINI Cooper?
On the MOT measure, the MINI Cooper: measured against cars of the same age, it comes out 7.9 percentage points ahead of the Ford Fiesta on first-time MOT passes, across 187,072 DVSA-recorded tests covering every generation on the road. A pass with rectification at the station counts as a pass here, and as a failure in DVSA's own initial-test measure. The MOT checks safety and emissions items, not the engine, clutch or gearbox, so this is one measure of how each car holds up rather than a full reliability verdict.
How do the MOT pass rates of the Ford Fiesta and the MINI Cooper compare?
72.3% of Ford Fiestas pass their MOT first time (143,495 tests in DVSA's records) and 87.2% of MINI Coopers pass their MOT first time (43,577 tests). The national first-time rate is 77.3%, but cars of the Ford Fiesta's age average 74.9% and cars of the MINI Cooper's age 81.9% — so the Ford Fiesta runs 2.6 points worse than its age group and the MINI Cooper runs 5.3 points better than its own. A pass with rectification at the station counts as a pass here, and as a failure in DVSA's own initial-test measure.
Which years of the Ford Fiesta and MINI Cooper should I avoid?
Ford Fiesta: Launch-era 2017–2018 cars are now the oldest Fiesta Mk8s on the used market and the most likely to still carry the original wet cam timing belt rather than Ford's later revised chain-driven design, so they're most likely to be nearing or past the belt's safe replacement point without full documented history. This window is also most associated with the early cracking-noise driveshaft complaint, and these cars are furthest removed from the 2022 facelift's refinements. The DVSA MOT table on this page rates 2018 registrations above all cars registered that year, so it is not named as a year to avoid. MINI Cooper: 2014–2015 cars are the ones owners most often report early crankshaft-bearing noise on (Cooper S petrol), diesels from these years fall inside the R/2020/179 and R/2023/174 EGR-cooler recalls, and they carry the highest mileage of any F56s on the used market today (making timing chain, water pump and clutch wear more likely to already be due), predate the 2018 infotainment/CarPlay update, and represent the first production year of an all-new platform with the usual early-build inconsistencies. The DVSA MOT table on this page rates 2014 and 2015 registrations above all cars registered those years, so they are not named as years to avoid. Judge a MINI Cooper by its registration, service history and the checks below rather than by year.
Is the Ford Fiesta or the MINI Cooper cheaper to run?
On fuel the Ford Fiesta has the edge: its most economical version returns up to 54 mpg, against up to 51 mpg for the MINI Cooper, on the figures in our model guides. For cars registered from April 2017, vehicle tax works the same way for both: the £200/year standard rate from the second year, hybrids included, plus the £440/year Expensive Car Supplement in years 2–6 on a car that listed at over £40,000 new — the price when new, not what you pay for it used. The electric versions (Cooper SE) pay the same £200/year standard rate since 1 April 2025 (electric cars were exempt before then), with the £440/year Expensive Car Supplement in years 2–6 only on one first registered from 1 April 2025 that listed at over £50,000 new. Any Ford Fiesta or MINI Cooper registered between 1 March 2001 and 31 March 2017 pays a CO2 band instead, roughly £20–£790/year (2026/27 rates). Insurance differs mainly by driver and postcode rather than by model, so treat any model-level insurance figure with caution.

MOT figures are counted from DVSA records and are the only measured statistic here. Prices, economy and tax bands are indicative and vary by specification, condition and where the car has lived. Last reviewed: 2026-10-06 / 2026-10-06.
