2017 Smart (mcc) Forfour 1.0L Petrol · NG17 DFX

The defining mechanical story of this Smart Forfour is one of consistent roadworthiness across its recorded test history, with eight consecutive passes stretching back to 2020 and no failures on file. The most recent assessment on 6 June 2026 returned a clean pass with no advisories or defects, which is a positive indicator, though it should be read alongside the broader pattern rather than in isolation. The single year where attention was drawn was the 2025 test, which produced four advisories concentrated on tyre condition and front brake pad wear. Outside of that one inspection, the car has passed without comment, including the clean 2024 and 2026 tests, suggesting that the items flagged mid-cycle were either addressed or were borderline observations rather than progressive faults. There is no history of suspension, steering, exhaust, structural, or lighting advisories, and no corrosion has been recorded, which is relevant given the Smart's lightweight construction and the age of the vehicle. With 63,373 miles recorded over approximately nine years, the annual accumulation sits at around 7,041 miles, broadly in line with typical usage for a vehicle of this age and type. There are no extended gaps in the testing record, with annual tests appearing consistently from 2020 onwards, including a mid-year test in May 2021 alongside the standard June 2021 entry, indicating the car has been in regular use rather than laid up. This continuity of testing, combined with a moderate annual mileage, suggests steady utilisation rather than periods of inactivity that might give rise to concerns about seized components, perished seals, or deteriorated brake systems. The mileage progression between tests does not indicate any unusual jumps that would warrant concern about odometer integrity or excessive high-mileage use between inspections. Given the advisory for offside front brake pads wearing thin recorded in June 2025, the immediate priority on inspection is the state of the front braking system. With approximately fifteen months of additional use since that advisory was raised, the pads are likely to have progressed further toward replacement, and on a test drive any squeal under light braking, a grinding sensation, or a warning on the dashboard should prompt closer examination. The condition and remaining tread depth of all four tyres warrant a physical check, as the 2025 advisories covered both nearside and offside fronts for cracking and perishing, alongside a nearside rear tyre that was close to the legal limit. Given the Smart Forfour's relatively small wheel and tyre package, uneven wear can also point to alignment or suspension issues, so any feathering across the tread or pulling under braking should be investigated. The 2023 advisory noting items removed from the driver's view prior to test is administrative in nature and carries no mechanical implication, but it is worth confirming on any physical inspection that there are no obstructions currently mounted on or near the windscreen that could similarly attract a defect. With no recorded advisories relating to suspension components, bushes, anti-roll bar links, or wheel bearings across the entire history, a test drive should still include a careful listen for knocks or clonks over speed humps and uneven surfaces, particularly at the front, as Smart vehicles of this era can develop wear in the lower suspension links and engine mounts. Steering should be checked for any notchiness or excessive free play, and the rear axle and trailing arms inspected for any signs of corrosion, even though none has been flagged to date. Overall, the mechanical picture presented by the MOT record is one of steady compliance with no chronic fault patterns, leaving the 2025 tyre and brake items as the principal items to verify in person before purchase.
