The 2018 Stonic is a subcompact crossover — seats five in a relatively compact footprint and usually comes with small-capacity petrol engines; many Irish examples are the 1.0 T‑GDi turbo or the naturally aspirated 1.2. As this is a petrol manual you won’t have DPF or AdBlue issues to worry about, but expect clutch wear over eight years and check whether any turbo‑charged examples show signs of oil consumption. Kia parts are widely available in Ireland and the Stonic has a generally strong reliability record, though the factory 7‑year warranty may be expired depending on the first registration date and mileage.

• Clutch and gearbox: take a long test drive and check for slipping, juddering or noisy synchromesh on gear changes.
• Turbo / oil (if 1.0 T‑GDi): check for excessive oil use, turbo whistle/grinding and that boost comes in smoothly; if it’s a 1.2/1.4 NA expect fewer turbo concerns.
• Suspension and tyres: listen for knocks over bumps and check for uneven tyre wear from misalignment or worn bushes.
• Boot and tailgate seals: inspect tailgate operation, boot lining and rear parcel shelf for water ingress or loose trim.
• Air‑con and electrics: check heater/AC performance, reversing camera/parking sensors and all interior switches for age‑related faults.
