Most 2019 CLA petrols are turbocharged small‑capacity engines paired with an automatic gearbox, so expect sharper performance than a small family hatch but higher running and servicing costs than mainstream brands. The CLA’s sloping roofline reduces rear headroom and boot practicality compared with a C‑Class or estate, and dealer servicing and genuine Mercedes parts are pricier but straightforward to source in Ireland.

• Automatic gearbox operation — check for smooth, consistent shifts, no hesitation or jerking and confirm any gearbox fluid/service history.
• Turbo and intake system — listen for turbo noise, check for boost loss/smoke and inspect intercooler/hose connections for leaks.
• Suspension and tyres — check for uneven tyre wear, creaks from suspension bushes or front wishbones and alignment issues from low‑profile tyres.
• Rear passenger space and boot — inspect rear headroom, seat cushion wear and parcel shelf/boot scuffs that reveal heavy use.
• Electrics and infotainment (MBUX) — verify camera, parking sensors, touchscreen, Bluetooth and any warning lights; note any pending software updates or stored fault codes.
