2017 Smart Forfour 1.0L Petrol · BO03 ALL

The vehicle remains roadworthy, though the maintenance trend shows a shift from consumable wear to emerging mechanical defects. The most recent test in October 2025 at 40,267 miles identified a minor exhaust gas leak from the silencer. While the car passed, the introduction of an exhaust fault after years of primarily tyre and brake advisories suggests components are beginning to degrade due to age rather than high-mile usage. The mileage profile is consistently low for a nine-year-old vehicle, averaging approximately 4,500 miles per year. Between October 2022 at 18,629 miles and October 2025 at 40,267 miles, the car covered 21,638 miles, indicating light use. This low-mileage history often implies less strain on the drivetrain and engine, but can also lead to rubber components hardening or brake components seizing if the vehicle has sat stationary for long periods between tests. A buyer must pay close attention to the braking system and tyres, as the record shows a recurring pattern of neglect. From 2022 to 2024, the tester repeatedly flagged thin brake pads, discs, and tyres worn to the 3mm limit. This suggests the previous owner only replaced these items when they reached the point of legal failure. The distorted offside front road wheel noted in 2022 should also be inspected for structural cracks or impact damage. The exhaust leak identified in the latest MOT requires immediate professional inspection to prevent it from failing the next test. Given the history of windscreen damage noted across multiple years, a physical check of the glass for further cracks that could compromise structural integrity is necessary. While the low mileage is an advantage, the recurring advisories for basic consumables indicate a reactive rather than proactive maintenance style that the new owner should verify.
