2018 Smart (mcc) Fortwo 1.0L Petrol · ET18 HBA

The vehicle presents a mixed maintenance profile, showing a recent decline in mechanical standards despite a clean pass in 2025. The June 2026 test at 69,850 miles initially resulted in a failure, highlighting several significant concerns. The tester identified an inoperative Engine MIL and an exhaust lambda reading outside specified limits, which points toward potential issues with the emissions control system or sensor functionality. The presence of thin front brake pads during this same test indicates that consumable maintenance is not being performed proactively. The mileage accumulation appears consistent with typical usage for an eight-year-old vehicle, averaging approximately 8,700 miles per year. The records show a steady increase from 22,108 miles in June 2021 to 69,850 miles in June 2026. This progression suggests regular road use rather than long periods of inactivity. However, the jump from 34,872 miles in June 2022 to 46,145 miles in June 2023 shows a slight increase in annual distance, though it remains within a predictable range for this type of city car. A buyer should prioritise a thorough inspection of the emissions system and engine management, given the recent failure regarding the lambda reading and the MIL status. While the vehicle passed the June 2026 test after repairs, the underlying cause of the exhaust emissions fault requires verification to ensure the catalytic converter or oxygen sensors are fully functional. The history of tyre wear, specifically the inner edge wear noted in June 2023 and the edge wear in June 2021, suggests possible wheel alignment issues or suspension component wear that should be checked. Brake maintenance also warrants attention. The vehicle failed in June 2022 due to thin front pads and failed again in June 2026 for the same reason. This recurring pattern suggests the previous owner tends to run consumables to their absolute limit rather than replacing them during scheduled servicing. A physical inspection of the brake discs for scoring and the pads for remaining thickness is necessary to ensure the braking system is currently in a reliable condition.
