The 2020 508 is the second‑generation liftback-style hatch with petrol engines commonly paired to PSA's 8-speed EAT8 automatic. The petrol/auto combination is smooth and refined for daily driving but will generally use more fuel on long motorway trips than a diesel; PSA issued software and service campaigns in the past for PureTech engines and automatic gearbox software, so confirm those were applied. Parts and servicing are straightforward to source in Ireland through main dealers and independent Peugeot specialists.

• EAT8 automatic gearbox behaviour — shifts should be smooth from cold, no harsh clunks, delayed engagement or limp‑home symptoms; ask for any gearbox‑fluid change or software update history.
• Engine oil condition and consumption — look for blue smoke on start, check oil level behaviour and any signs of oil leaks around the turbo/head area.
• Confirm PSA recall and TSB history for PureTech petrol engines and EAT8 software updates have been completed.
• Rear roofline and tailgate seals — the low fastback profile can trap water around the tailgate/boot seals, so check for damp, broken tailgate struts or worn parcel‑shelf fixings.
• Front suspension and brakes — listen for knocks from bushes on rough roads and inspect front discs for scoring and pads for even wear.
