2013 Smart Fortwo Passion MHD Auto 1.0L Petrol · WX63 XKB

The vehicle presents a mixed but currently stable roadworthiness profile following its most recent MOT on 19 September 2025 at 42,235 miles. That final pass came after an initial failure on the same day flagged a non-functioning nearside stop lamp and both rear brake pipes corroded and contaminated with grease or other material, alongside a badly cracking offside rear tyre. The immediate retest cleared those items, suggesting the owner addressed the defects promptly. However, the pattern across the full history reveals a recurring and persistent corrosion issue at the rear brake pipes, and repeated tyre perishing advisories, which a buyer should treat as a long-term maintenance vulnerability rather than a one-off fix. The mileage accumulation is notably low for a 2013 vehicle. Between the 2022 test at 35,408 miles and the 2023 test at 37,004 miles, the car added just 1,596 miles in twelve months. The gap widened only slightly to 3,286 miles between September 2023 and September 2024, then flattened dramatically to 1,945 miles between 2024 and the final 2025 test. This trajectory suggests prolonged periods of very light use or standing, which is consistent with the corrosion-related defects appearing on a vehicle that has covered relatively few miles. Low mileage alone does not protect brake components from moisture ingress and internal fluid deterioration, particularly on a short-wheelbase city car likely exposed to urban road salt. The recurring rear brake pipe corrosion advisories, escalating from slight corrosion noted on 18 September 2023 at 37,004 miles to full failure-level corrosion on both sides by 19 September 2025, point to either inadequate pipe routing, degraded protective coating, or moisture trapped under accumulated grease. A buyer should have a technician inspect the full rear brake line run, including flexible hoses and unions, for wall thinning and contamination. The repeated tyre cracking advisories on both the nearside and offside rear tyres across multiple years raise questions about storage conditions, UV exposure, or age-related rubber degradation rather than simple wear. Any replacement tyres should be checked for date codes, as perished sidewalls can fail without warning. Beyond the MOT-recorded items, the low annual mileage and corrosion pattern warrant a close underbody inspection. Suspension mounting points, subframe mounting areas, and the rear floor pan should be examined for surface rust or pitting that can develop on vehicles sitting unused for extended periods. The MHD system and its associated brake energy recovery components should also be verified for proper operation, as infrequent use can cause caliper seizure or sticking that standard MOT observations may not fully capture. Overall, the maintenance trend is not worsening, but the underlying corrosion susceptibility remains unresolved and demands ongoing vigilance.
