Most 2017 Polos on petrol use the small 1.0 TSI three‑cylinder or older naturally aspirated petrols; both are economical but the TSI needs correct oil grades and regular oil-change intervals. You’ll commonly see 5‑ or 6‑speed manuals — simple and durable, but clutch wear is the main driveline item to watch on a nine‑year‑old city car. Parts and independent servicing are easy to find in Ireland, which keeps running costs reasonable.

• Clutch engagement and slipping under load — check biting point and for judder which shows wear or a worn dual-mass flywheel.
• Listen for rattling/ticking at cold start or when revving (possible timing‑chain/tensioner noise on some 1.0 TSI engines) and look for signs of oil leaks or excessive oil consumption.
• Manual gearbox shifts smoothly through all gears with no crunching or missed syncros, especially into 2nd and 3rd.
• Suspension and steering — check for knocks from worn drop‑links, anti‑roll bar bushes or tie‑rod ends and look for uneven tyre wear.
• Rear wheel‑arch seams and door bottoms for corrosion or bubbling paint; small hatchbacks that do lots of town miles can show seam rust by this age.
