This is the 10th‑generation Civic sold in Europe with the 1.6 i‑DTEC diesel and a 6‑speed manual — a good motorway cruiser with strong real-world MPG. Key things to watch on diesel Hondas of this era are the DPF and EGR/turbo system (they want regular long runs to stay healthy) and the clutch on a six-year-old manual. Diesel demand is softer now, so resale and tax/emissions considerations matter in Ireland.

• DPF condition and regeneration history — look for frequent warning lamps, heavy soot on the tailpipe or a record of forced regens; ask whether the car has done regular long motorway miles.
• EGR/turbo behaviour — check for turbo lag, black smoke on hard acceleration, hissing from boost hoses and any oil leaks around the turbo/intercooler joints.
• Clutch wear and operation — test for slipping under load and look for a high or inconsistent bite point during a sustained drive.
• Manual gearbox feel — ensure smooth selection through all gears with no crunching or false neutrals, especially 2nd/3rd which can show synchro wear.
• Underbody and rear wheel-arch corrosion — inspect exhaust hangers, rear subframe and sill areas for surface or progressing rust from Irish road salt exposure.
