Toyota Yaris vs Volkswagen Polo: which is the better used buy?
On DVSA MOT records the Toyota Yaris is the more reliable used buy: it passes its first MOT 6.8 percentage points more often than the Volkswagen Polo once both are compared against what the national fleet scores at the same age. That comparison covers 115,896 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.
| Model | Pass rate | Age-matched national | Difference | Tests |
|---|---|---|---|---|
| Toyota Yaris | 79.5% | 75.7% | +3.8 | 49,396 |
| Volkswagen Polo | 72.7% | 75.8% | -3 | 66,500 |

Toyota Yaris
XP210, 2020+ · supermini hybrid hatch
The XP210 Toyota Yaris Hybrid (2020+) is among the most reliable cars sold in the UK. The hybrid system is solid; minor concerns are early-batch AC compressor failures, the 12V auxiliary battery on cars left unused, and brake squeak (cosmetic, common across all hybrids). The pre-2020 XP130 had rear-beam corrosion in coastal areas — XP210 unaffected. Best-buy: any year. Worst: none.
What goes wrong
- AC compressor (early-batch)moderateAC blows warm; clicking from compressorEarly 2020 production · £650–£950 compressor + regasCheck: Test AC during inspection — should be cold within 1 minute on a warm day.
- 12V auxiliary battery (unused cars)minorHybrid system won't wake; "READY" not appearingAll XP210 · Battery age 4–5 years · £220–£350Check: Toyota battery health check at dealer (£20–£30).
- Brake squeak (regen)minorSqueak at low speeds, fades with speedAll hybrids · CosmeticCheck: Common, not a fault.
- Touch 2 infotainment lagminorSlow CarPlay response2020–2022 · No fix — software limitationCheck: Use 10+ minutes during test drive to assess if liveable.
- Typical asking price:
- £14,000–£22,000 (2020–2024)
- Real-world economy:
- 63–74 mpg hybrid — best-in-class
- 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).

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)criticalChain rattle on cold start; engine warning light (timing-related codes); rough running; in severe cases, engine failure2017–2018 (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 occurredCheck: 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 juddermajorShudder when moving off from standstill; jerkiness at low speed in traffic; clutch grab in 1st gear2017–2022 (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 replacementCheck: 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 issuesminorTouchscreen freezes or goes blank; Bluetooth disconnects; screen reboot on startup2017–2020 (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)minorAdBlue warning light; countdown to engine start lockout; "Top up AdBlue" warnings2017–2021 (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 failsCheck: 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

- 2017, 2018
Which one suits you
Toyota Yaris
Good for: Urban drivers, first-time buyers, anyone prioritising lowest running costs.
Less good for: Long-distance highway commuters wanting cabin space.
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.
