2014 C‑Class sits on the boundary between the outgoing W204 and the new W205 generation; most 2014 cars you see will be saloons or estates rather than hatchbacks, so confirm body style. Petrol/manual examples typically use a small‑capacity turbo petrol (1.6–2.0) with a 6‑speed manual — no diesel DPF to worry about, but clutch and gearbox wear are the main drivetrain concerns. Mercedes parts are widely available in Ireland but dealer servicing is pricier; independent Mercedes specialists do good value work if you want to save on servicing.

• Clutch engagement and pedal feel for slipping or a high bite point; replaceable clutch or dual‑mass flywheel work can be costly on a 12‑year‑old car.
• Manual gearbox for crunching or noisy synchros (especially 2nd/3rd) and smooth selection through all gears.
• Rear suspension/subframe and trailing‑arm bushings for corrosion or wear; if the car has Airmatic/air suspension check for sagging, compressor noise or uneven ride.
• Electrics and trim: window regulators, central locking, infotainment and boot/tailgate seals (electrical gremlins and water ingress are common on older German cars).
