Ford Fiesta vs Vauxhall Corsa: which is the better used buy?

On DVSA MOT records the Ford Fiesta does better at its MOT: measured against cars of the same age, it comes out 2.4 percentage points ahead of the Vauxhall Corsa on first-time MOT passes. That comparison covers 237,896 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 Vauxhall Corsas registered 2001–2022.

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.

  • 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.

Vauxhall Corsa

Mk5 (E) 2014–2019, Mk6 (F) 2019+ · supermini / city hatch

The Vauxhall Corsa Mk6 (2019+) uses the PSA 1.2 PureTech engine, which is efficient but runs its timing belt in engine oil — the "wet belt" that has caused engine failures across Peugeot, Citroën and Vauxhall. Stellantis cut the interval to 6 years or 62,000 miles, so what matters is whether the belt has been done, not the model year. The older Mk5 (2014–2019) with the 1.4 non-turbo petrol avoids the issue; its Easytronic automated-manual is the main risk. Best-buy: Mk5 1.4 manual, or a Mk6 with a documented belt change.

  • 1.2 PureTech wet timing belt (Mk6)critical
    Oil level dropping between services; rattle or whine on cold start; engine warning light; in the worst case sudden oil-pressure loss and engine failure
    2019–2023 Mk6 (1.2 PureTech petrol — the wet belt was phased out for a chain from 2023) · Belt is due at 6 years or 62,000 miles, whichever comes first — failures cluster on cars that passed it · £450–£850 at a UK independent for the belt including cleaning the oil pick-up; £4,000+ if the belt has already shed debris and starved the engine
    Check: This engine runs its timing belt submerged in engine oil. As the belt ages it sheds rubber particles, and those particles block the oil pick-up strainer — so the belt does not usually snap, it starves the engine instead. Ask one question: has the belt been changed, and is there an invoice? Stellantis revised the interval down to 6 years or 62,000 miles with annual oil changes on the correct 5W-30, so a 2019–2020 car is at or past it now. Pull the dipstick and treat a low level as a red flag. Stellantis also runs a UK compensation portal covering qualifying wet-belt repairs paid for between January 2022 and December 2024, and a warranty extension of up to 10 years / 112,000 miles on these engines — worth checking before you accept any quote.
  • Easytronic automated-manual (Mk5)major
    Hesitation and shuddering in slow traffic; clutch actuator warning; slow gearchanges
    Mk5 with Easytronic (not the 5-speed manual) · 50,000+ miles · £600–£1,200 clutch actuator + clutch plate; full Easytronic overhaul £1,500+
    Check: Test drive in stop-start traffic only. Smooth clutch engagement on pull-away is the test. Any shudder = actuator worn. Check exactly which gearbox is fitted — Easytronic vs manual via VIN.

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.

Vauxhall Corsa

Good for: First-time buyers on a budget; urban commuters; buyers wanting low running costs. The Mk5 1.4 manual is the most forgiving used car buy in the UK under £10,000.

Less good for: Anyone considering a 2019–2020 Mk6 1.2 PureTech without confirmed service history — the wet timing belt risk is real. Buyers needing a car primarily for motorway miles (too small for comfort).

Frequently Asked Questions

Which is more reliable, the Ford Fiesta or the Vauxhall Corsa?
On the MOT measure, the Ford Fiesta: measured against cars of the same age, it comes out 2.4 percentage points ahead of the Vauxhall Corsa on first-time MOT passes, across 237,896 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 Vauxhall Corsa compare?
72.3% of Ford Fiestas pass their MOT first time (143,495 tests in DVSA's records) and 71.0% of Vauxhall Corsas pass their MOT first time (94,401 tests). The national first-time rate is 77.3%, but cars of the Ford Fiesta's age average 74.9% and cars of the Vauxhall Corsa's age 76.0% — so the Ford Fiesta runs 2.6 points worse than its age group and the Vauxhall Corsa runs 5.0 points worse 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 Vauxhall Corsa 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. Vauxhall Corsa: 2019–2020 Mk6 cars are now past the revised 6-year/62,000-mile belt interval, and this is the failure that matters: the belt degrades in the oil, the debris blocks the oil pick-up, and the engine is starved rather than the belt snapping. A car of these years with no belt invoice is carrying an open-ended risk, and repair once debris has circulated runs well beyond the cost of the belt itself.
Is the Ford Fiesta or the Vauxhall Corsa cheaper to run?
On fuel the Ford Fiesta has the edge: its most economical version returns up to 54 mpg, against up to 49 mpg for the Vauxhall Corsa, 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. Any Ford Fiesta or Vauxhall Corsa 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.
