2015 Smart Forfour 1.0L Petrol · LM15 GOH

The 2015 Smart Forfour presents a stable and improving maintenance picture as of its most recent test. The May 2026 MOT at 80,403 miles passed cleanly with zero defects, a notable turnaround from the April 2025 failure just days before its pass. That failure flagged a fractured offside front coil spring and an inoperative engine MIL, both serious items that have since been rectified. The Lambda reading issue on the same test also cleared, suggesting the exhaust or fuelling system received attention. This pattern indicates a reactive but effective repair approach rather than neglect. The mileage accumulation is consistent and unremarkable for an 11-year-old city car, averaging roughly 7,300 miles annually. The 2025 tests bracket a narrow window: the failure at 80,222 miles on April 15 and the pass at 80,225 miles on April 22, confirming the defects were addressed within a week. The gap between April 2025 and May 2026 shows only 178 miles added over thirteen months, pointing to very light recent use or a period of limited activity. The 2024 to 2025 interval covered roughly 249 miles, reinforcing that this vehicle has been driven sparingly in recent years. A buyer should focus the physical inspection on the front suspension and braking components. The fractured coil spring in April 2025 raises questions about the condition of the nearside unit and the general state of the suspension bushes and dampers, particularly given the anti-roll bar linkage play noted in May 2024. The front brake discs were flagged as worn and pitted in 2024, so checking for uneven wear, lipping, and disc thickness remains worthwhile. The 2023 advisory on a damaged and insecure undertray warrants a look underneath for fresh corrosion, loose mounting points, or exhaust heat shield deterioration. Tyre condition should also be verified, given the repeated tread and sidewall warnings in 2023, especially if the car has covered minimal mileage since then and tyres have aged rather than worn.
