This is the Astra J generation (facelifted models were still current in 2015) commonly fitted with small-capacity petrol engines and a 5-speed or 6-speed manual. Petrol models avoid DPF/EGR headaches that diesels can have, but look for clutch wear on an 11‑year‑old manual and check whether the particular petrol engine uses a timing chain or belt and its service history. Electrical niggles on infotainment/door modules are the most common minor annoyances on older Astras.

• Clutch engagement and pedal feel — test for slipping under load and check for high bite point (manual-specific).
• Gearbox synchro: listen for crunching or reluctance into 2nd/3rd/4th when cold and on a test drive.
• Confirm timing system type and replacement history — if belt-driven confirm timing-belt change intervals have been met; if chain-driven listen for rattles at cold start/tick-over.
• Suspension and bushes: check for knocks from front strut mounts, anti-roll bar links and worn rear trailing-arm bushes on rough roads.
• Rust check around rear arches, sills and the underside of the boot floor — common on 11-year-old cars in Irish conditions.
