2005 Smart Fortwo Coupe 0.7L Petrol · KN05 WTY

The most recent MOT on 23 October 2024 was passed with no recorded defects, following a clean pass on 3 January 2023. The only blemish in the three‑year record is an advisory from the 1 December 2021 test noting a non‑excessive oil leak (8.4.1 (a)(i)). Overall the vehicle’s maintenance trend appears stable; the leak has not progressed to a failure condition, but it remains a point that should be verified before purchase. At 122 240 miles the Smart Fortwo has averaged roughly 5 800 miles per year over its 21‑year lifespan, which is considerably below the typical usage for a small city car. Such low annual mileage often indicates either very light daily use or prolonged periods of storage. While the reduced wear on the drivetrain, brakes and suspension is beneficial, components that age with time rather than distance—rubber seals, hoses, bushings and the body structure—may have deteriorated despite the modest mileage. Any long gaps between services should be noted, as they can allow corrosion or fluid degradation to progress unnoticed. When inspecting the vehicle, give particular attention to the source of the oil leak noted in 2021. Examine the engine bay and under‑carriage for fresh oil stains, especially around the valve cover gasket, oil filter housing and the rear main seal. Verify that the oil level is correct and that there are no oil droplets on the spark plug wells or on the exhaust manifold, which would indicate a worsening leak. During a test drive listen for any low‑frequency droning that could be caused by oil splashing onto moving parts, and watch for any smoke or oil vapour from the exhaust. Because the car has been lightly used for many years, age‑related checks are essential. Inspect the tyre sidewalls for cracking, dry rot or delamination and confirm the tread depth is still within legal limits; tyres older than six years should be considered for replacement regardless of wear. Assess the 12 V lead‑acid battery for voltage and cranking performance, as a two‑decade‑old unit is likely near the end of its service life. Look for corrosion on the chassis, wheel arches and exhaust system, and feel the suspension bushes and coil springs for hardness or cracking that can cause clunking or uneven ride quality. Examine the brake discs for surface rust or scoring and ensure the pads are not excessively worn; binding calipers can develop when a car sits for long periods, leading to brake shudder or pull. Finally, confirm that coolant, brake fluid and gearbox oil have been changed within their recommended calendar intervals (typically every two years for brake fluid) and that a recent service stamp is present in the logbook. These checks will give a realistic picture of the car’s mechanical health beyond what the MOT record alone reveals.
