Begin with a visual inspection of the bodywork, focusing on the wheel arches, sills and lower panels for any signs of rust or paint bubbling, especially given the car's age. Check the condition of the suspension components, including bushes and shock absorbers, as worn suspension is a common issue on higher‑mileage Mazda 3s. Verify the operation of the timing chain by listening for rattling noises at start‑up, and inspect the oil filler cap and dipstick for any milky residue indicating coolant leakage.

Examine the interior for wear on the seats, dashboard and steering wheel, and test all electronic functions such as the infotainment system, windows and lights. Confirm that the tyre tread depth meets the legal minimum of 1.6 mm and assess overall tyre condition, as uneven wear can hint at alignment or suspension problems. Finally, review the MOT certificates for any advisory notes that were not addressed before the test, and ensure the vehicle has a valid service history that matches the mileage intervals.
