Vauxhall Corsa vs Volkswagen Polo: which is the better used buy?

On DVSA MOT records the Volkswagen Polo is the more reliable used buy: it passes its first MOT 2.0 percentage points more often than the Vauxhall Corsa once both are compared against what the national fleet scores at the same age. That comparison covers 160,901 real tests, not a survey.

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. It is a service item, not a lottery: 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 naturally aspirated petrol avoids the issue entirely and is near-bulletproof; its Easytronic automated-manual is the only real risk. Best-buy: Mk5 1.4 manual, or a Mk6 with a documented belt change.

What goes wrong

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.
Electric power steering (EPS) failuremoderate
"Power Steering" warning; heavy steering; loss of assistance at low speeds
Mk5 and early Mk6 · 60,000+ miles · £450–£900 EPS motor or control unit
Check: Test power steering at parking lot speeds. Should be effortless. Any heaviness or warning = EPS issue.
Brake booster failure (Mk5)moderate
Hard brake pedal requiring heavy foot pressure; longer stopping distances
Mk5 2014–2019 · 75,000+ miles · £350–£600
Check: Press brake pedal firmly several times with engine off — should feel firm but not rock-hard when engine starts. Hard pedal with engine running = booster suspect.

Typical asking price:: Mk5: £3,500–£9,000 | Mk6: £8,000–£18,000 (2019–2023)

Volkswagen Polo

Mk6 AW (2017–present) · B-segment supermini. Consistently one of the top 5 best-selling used cars in the UK. The Mk6 Polo brought Golf-like interior quality to the supermini segment. Available with 1.0 MPI (naturally aspirated), 1.0 TSI (turbocharged), and 1.6 TDI diesel engines.

The VW Polo Mk6 is a premium-feeling supermini with solid reliability when maintained. The 1.0 TSI petrol is the engine to choose — reliable, tax-friendly, and economical. The main concern on Mk6 Polos is the timing chain on early 1.0 TSI engines (pre-2019), which can stretch if oil changes are delayed. The 7-speed DSG dual-clutch automatic has judder issues in urban use above 30,000 miles. Avoid the 1.6 TDI diesel for city use (DPF). A well-maintained 2019+ Polo 1.0 TSI manual is one of the safest sub-£20,000 used superminis on the UK market.

What goes wrong

1.0 TSI timing chain stretch (early production)critical
Chain rattle on cold start; engine warning light (timing-related codes); rough running; in severe cases, engine failure
2017–2018 (1.0 TSI 95 and 115 PS) · From 35,000 miles if oil changes were delayed; can appear earlier with incorrect oil specification · £600–£1,500 timing chain kit; up to £4,000+ if engine damage has occurred
Check: Listen for chain rattle on cold start (first 10 seconds). Check the oil change history — the 1.0 TSI requires oil changes every 9,300 miles or 12 months maximum (not 20,000 miles longlife intervals). Longlife oil change intervals are a major risk factor. Ask if the chain has been replaced or inspected. On 2017–2018 cars specifically, ask for proof of oil change compliance.
7-speed DSG dual-clutch juddermajor
Shudder when moving off from standstill; jerkiness at low speed in traffic; clutch grab in 1st gear
2017–2022 (7-speed DQ200 DSG automatic) · Above 30,000 miles in urban use; earlier if no DSG service has been carried out · £400–£700 DSG fluid and filter service + software recalibration; £1,500–£3,000 if mechatronic unit or clutch pack needs replacement
Check: Test the DSG at walking pace in slow traffic and pulling away from a standstill on an uphill. Any shudder is the known DQ200 judder — very common on Polo, Golf, and other VAG models with this gearbox. VW schedules no oil service for the dry-clutch DQ200, so absent DSG fluid records are normal rather than a red flag; a voluntary mechatronic oil service (some specialists suggest around 60,000 miles) can ease mild judder. Severe judder at low mileage without service history is a red flag.
Infotainment MIB2 system freeze and Bluetooth issuesminor
Touchscreen freezes or goes blank; Bluetooth disconnects; screen reboot on startup
2017–2020 (MIB2 infotainment) · Not mileage-related — software issue · £0 — VW dealer software update resolves most issues; hardware replacement rare (£300–£600 if required)
Check: Test the touchscreen and Bluetooth during the test drive. MIB2 system freezes are resolved by a free dealer software update in most cases. Ask if the infotainment system has had the latest VW software applied.
AdBlue system faults (1.6 TDI diesel)minor
AdBlue warning light; countdown to engine start lockout; "Top up AdBlue" warnings
2017–2021 (1.6 TDI) · Every 9,300–10,000 miles (consumable — not a fault) · £15–£25 for 5L AdBlue top-up; £200–£600 if NOx sensor or SCR catalyst fails
Check: Check the AdBlue level if buying a TDI variant. AdBlue is a consumable — low warning is normal. However, NOx sensor failures are more common on higher-mileage TDI Polos. Check whether the engine management light is on.

Typical asking price:: Mk6 2017–2019: £6,000–£11,000 | Mk6 2020–2022: £9,000–£16,000
Real-world economy:: 44–51 mpg (1.0 TSI real-world UK mixed); 57–67 mpg (1.6 TDI real-world)
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

Which one suits you

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 timing chain risk is real. Buyers needing a car primarily for motorway miles (too small for comfort).

Volkswagen Polo

Good for: Buyers who want Golf-level interior quality in a smaller package. Urban commuters who primarily use the car in town (1.0 TSI manual is ideal for this). Buyers who want strong resale value — VW Polos hold value well on the UK market.

Less good for: Buyers doing heavy city driving with the DSG automatic without a DSG service budget. 2017–2018 1.0 TSI buyers who cannot verify oil change compliance and chain condition. City-only drivers considering the 1.6 TDI — DPF issues are near-certain. Buyers who want the most reliable possible supermini should consider the Toyota Yaris Hybrid.

Frequently Asked Questions

Which is more reliable, the Vauxhall Corsa or the Volkswagen Polo?

The Volkswagen Polo. It passes its first MOT 2.0 percentage points more often than the Vauxhall Corsa once both are age-adjusted, across 160,901 DVSA-recorded tests.

What is the MOT pass rate for the Vauxhall Corsa?

71% of Vauxhall Corsas pass their MOT first time, from 94,401 tests in DVSA's records. The national first-time rate is 77.3%, but cars of this model's age average 76% — so it runs 5 points worse than its age group.

What is the MOT pass rate for the Volkswagen Polo?

72.7% of Volkswagen Polos pass their MOT first time, from 66,500 tests. Against the 75.8% that cars of its age average, it runs 3 points worse.

Which years should I avoid?

For the 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. For the Volkswagen Polo, 2017–2018 launch cars had the highest incidence of 1.0 TSI timing chain stretch complaints — particularly where oil change intervals were extended or low-quality oil was used. DSG judder on early automatics was also more pronounced before software calibration updates.

Which is cheaper to run?

The Vauxhall Corsa returns 1.2 PureTech: 40–49 mpg. 1.4 N/A (Mk5): 36–44 mpg in real UK driving; the Volkswagen Polo returns 44–51 mpg (1.0 TSI real-world UK mixed); 57–67 mpg (1.6 TDI real-world). Vehicle tax: Corsa — £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).; Polo — £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).. Insurance differs mainly by driver and postcode rather than by model, so treat any model-level insurance figure with caution.
