Ford Focus vs Toyota Corolla: which is the better used buy?

On DVSA MOT records the Toyota Corolla is the more reliable used buy: it passes its first MOT 4.1 percentage points more often than the Ford Focus once both are compared against what the national fleet scores at the same age. That comparison covers 106,195 real tests, not a survey.

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.

Ford Focus	74.7%	74.8%	-0.1	93,066
Toyota Corolla	84.6%	80.5%	+4	13,129

Ford Focus

Mk4, 2018–2025 · compact family hatch

The Mk4 Ford Focus (2018–2025) drives brilliantly, but the 1.0 EcoBoost wet belt remains the critical check — the design caused engine-destroying failures on the previous Mk3 generation, and while Mk4 belts are revised, they are still a wear item that must be inspected or changed at 60,000 miles or 7 years. The 1.5 EcoBlue diesel suffers oil dilution on short journeys. Best-buy: 1.0 EcoBoost 2021+ with documented belt evidence. Worst: early Mk4 (2018–2019) 1.0 EcoBoost with no belt history.

What goes wrong

1.0 EcoBoost wet-belt failurecritical
Loss of compression; check engine; belt debris in oil; in worst case complete engine destruction
All Mk4 1.0 EcoBoost — early cars (2018–2019) highest risk; belts revised on later builds · Belt should be inspected/changed at 60,000 miles or 7 years · Belt + tensioner + labour: £700–£1,100 preventatively. Engine rebuild after failure: £4,500–£7,000.
Check: Service history MUST show wet-belt change at correct interval. No record = walk away. Oil pan inspection at independent garage is the best confirmation.
1.5 EcoBlue diesel oil dilutionmajor
Engine oil level rising between services; oil smells of diesel
1.5 EcoBlue diesel, all years · Service interval reduction; in worst cases injector replacement £600–£1,200
Check: Dipstick check pre-purchase: if oil level above max line, oil dilution is occurring.
Rear suspension bushing wearminor
Knocking over rough surfaces; vague handling
All Mk4 · 75,000+ miles · £250–£450
Check: Rough-road portion of test drive.
SYNC 3 / SYNC 4 infotainment glitchesminor
Screen freezes; CarPlay disconnects; reboot needed
2018–2021 · Free at Ford dealer software update
Check: Test infotainment fully during inspection.

Typical asking price:: £11,000–£22,000 (2018–2025)
Real-world economy:: 44–51 mpg real-world for 1.0 EcoBoost 125PS
Vehicle tax:: £200/year standard rate from the second year, hybrids included — the alternative-fuel discount ended on 1 April 2025. Cars registered 2001–2017 pay a CO2 band, roughly £20–£790/year (2026/27 rates).
Best years:: 2021, 2022, 2023
Years to avoid:: 2018, early 2019

Toyota Corolla

E210, 2019+ · compact hybrid hatch and saloon

The E210 Toyota Corolla Hybrid (2019+) is the most reliable car in its class in the UK. The hybrid system is solid to 125,000+ miles. Minor concerns are rear shock corrosion in coastal areas, an inverter coolant pump recall on some examples, and Touch 2 infotainment lag (cosmetic). Best-buy: any year. Worst: none — exceptional consistency.

What goes wrong

Inverter coolant pumpmoderate
"Hybrid system check" warning; reduced EV-only operation
2019–2020 (recall on some VINs) · Free under recall; £450 otherwise
Check: Verify recall completion via VIN with Toyota UK or the gov.uk recall checker.
Rear shock corrosion (coastal areas)minor
Rust around shock mount; advisory on MOT
All E210 in coastal areas (e.g. the west coast, Scotland, the South West) · Time-driven, typically 5+ years · £200–£350
Check: Underbody inspection at viewing — bring a torch.
Touch 2 infotainment lagminor
Slow response to taps; CarPlay reconnect needed
2019–2022 (Touch 2) · No fix — software limitation. Toyota Smart Connect (post-2023) is significantly better.
Check: Use infotainment for 10+ minutes during test drive — assess if you can live with the lag.
Hybrid 12V auxiliary batteryminor
Cars not used regularly may struggle to wake the hybrid system
All E210 · Battery age, typically 4–5 years · £220–£350 battery replacement
Check: Toyota battery health test at Toyota dealer (£20–£30 if not free).

Typical asking price:: £16,000–£28,000 (2019–2024)
Real-world economy:: 59–71 mpg real-world hybrid — best-in-class on UK roads
Vehicle tax:: £200/year standard rate from the second year, hybrids included — the alternative-fuel discount ended on 1 April 2025. Cars registered 2001–2017 pay a CO2 band, roughly £20–£790/year (2026/27 rates).
Best years:: 2019, 2020, 2021, 2022, 2023, 2024
