Hyundai i30 vs Volkswagen Golf: which is the better used buy?

On the MOT measure, the Volkswagen Golf: measured against cars of the same age, it comes out 7.4 percentage points ahead of the Hyundai i30 on first-time MOT passes, across 101,579 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.

71.2% of Hyundai i30s pass their MOT first time (10,713 tests in DVSA's records) and 79.2% of Volkswagen Golfs pass their MOT first time (90,866 tests). The national first-time rate is 77.3%, but cars of the Hyundai i30's age average 75.0% and cars of the Volkswagen Golf's age 75.6% — so the Hyundai i30 runs 3.8 points worse than its age group and the Volkswagen Golf runs 3.6 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.

Hyundai i30: Early 1.4 T-GDI examples (2018–2019) are the ones owners most often report oil pressure warnings and injector issues on. How often it happens is not known. The 7-speed dry-clutch DCT on these variants also had calibration issues causing low-speed judder in urban traffic — particularly frustrating for city commuters. Volkswagen Golf: Mk8 2020–2022 infotainment software is the most reported complaint on owner forums, and Volkswagen issued software updates for it. Hardware combined with early software made the cabin frustrating. The same cars are also inside DVSA recall R/2024/014: on Golfs built 6 March 2020 to 31 August 2022 with the electromechanical brake servo and DSG, a heat-protection mat may have been fitted wrongly and the brake-fluid reservoir can melt and leak into the engine bay (26,721 vehicles in the whole recall, shared with the Passat and Arteon). Check the registration. The DVSA MOT table on this page rates 2020, 2021 and 2022 registrations above all cars registered those years, so they are not named as years to avoid. Judge a Golf by its registration, service history and the checks below rather than by year.

On fuel the two are too close to call: the most economical versions return up to 59 mpg (Hyundai i30) and 57 mpg (Volkswagen Golf), 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 Hyundai i30 or Volkswagen Golf 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.
