2017 Smart (mcc) Fortwo 0.9L Petrol · LL17 UJC

A 2017 Smart ForTwo carrying a consecutive run of five unblemished MOT passes, most recently cleared on 13 November 2025 with no advisories or failures recorded, presents a reassuringly straightforward roadworthiness picture for its age. The absence of any defect entries across the entire testing history is uncommon for a nine-year-old city car and indicates that none of the items typically scrutinised at annual test, from braking components and suspension linkages through to lighting, tyres and exhaust integrity, have yet reached a serviceable or borderline condition in the examiner's judgement. This clean sheet does not guarantee that mechanical components are in prime order, as the MOT is a point-in-time safety and emissions check rather than a comprehensive mechanical inspection, but it does establish a baseline of consistent compliance with roadworthiness standards throughout the vehicle's documented life. The recorded mileage of 23,785 miles against a nine-year registration works out to an annual accumulation of roughly 2,640 miles, which sits firmly in low-use territory for any passenger car and is particularly modest for a Smart ForTwo given its intended role as an urban runabout. Such a figure points to predominantly short, light-duty trips rather than sustained motorway use, and mechanically this generally means reduced wear on major drivetrain components, brake friction materials and clutch assemblies, while placing greater relative stress on items affected by infrequent operation, including the rear-mounted engine's cooling system, exhaust condensate management, brake discs through lack of regular drying heat cycles, and any rubber or polymer parts prone to perishing from prolonged standing. There are no gaps in the MOT testing record, confirming the vehicle has remained in continuous use and on the road throughout the period under review, and the mileage progression appears broadly consistent rather than showing any sudden spikes or unexplained jumps that might warrant concern. For a prospective buyer, the test drive should focus on the symptoms most commonly associated with low-mileage city cars of this type rather than relying on the clean MOT alone. Pay close attention to the steering response: the Smart ForTwo uses a direct rack-and-pinion set-up and any knocking, looseness or uneven self-centring as the wheel is turned lock-to-lock could point to worn track rod ends or drop links that would not necessarily have been flagged at test. Listen for any clonking or creaking from the rear suspension over speed humps and uneven surfaces, as the De Dion rear axle and its trailing arms, bush assemblies and coil springs carry the majority of the vehicle's load and are susceptible to deterioration from age even at low mileages. On the move, check for any pulling to one side under braking, uneven pedal feel or a soft, spongy pedal that may indicate sticking caliper slides or a binding rear drum mechanism, all of which can develop through infrequent operation. Given the Smart's rear-engine layout and turbocharged 0.9-litre petrol unit on the 2017 facelift variant, a thorough inspection should include checking for any oil seepage around the turbocharger and intercooler pipework, as well as listening for an irregular idle or any hesitation that could suggest carbon build-up from predominantly short-trip usage. With the engine running from cold, watch the exhaust for excessive vapour or a distinct sweet smell that may point to failing head gasket seals, and confirm that the cooling fan cuts in at the correct temperature, since the compact rear bay can trap heat. Brake discs should be inspected for any significant lipping or surface corrosion around the outer edge, a common finding on lightly used cars, and the handbrake mechanism should be tested on an incline to confirm clean ratchet action. Finally, verify that the service history matches the recorded mileage and includes timely replacement of the timing belt, which on this engine is a critical maintenance item, and confirm that the Mercedes-Benz Smart specialist network or suitably equipped independent garage has attended to the vehicle rather than generalist workshops unfamiliar with the marque's specific service procedures.
