2003 Smart (mcc) Cabriolet 0.7L Petrol · GM03 MUZ

The 2003 SMART cabriolet presents a concerning roadworthiness picture marked by a cluster of recurring advisories and a single serious failure that has not yet been resolved. The most recent MOT on 2023-03-15 returned a pass despite a collection of issues including an oil leak of moderate severity, rusty brake discs attributed to prolonged standing, a corroded brake pipe, a minor exhaust gas leak, and a failing exhaust system. Earlier in 2013 the vehicle suffered a complete failure when the front brake disc was found to be seriously weakened, the horn was non-functional, the exhaust suffered a major leak, emissions could not be tested, and the windshield washer system was inadequate. Between the 2013 failure and the 2023 pass, ten years elapsed without another MOT, raising questions about the condition of the powertrain and chassis during that extended period, and the persistence of oil leakage and disc corrosion through 2023 indicates ongoing underlying problems that have not been properly addressed. At 73,888 miles on a vehicle that is approximately 23 years old, the recorded mileage represents an unusually low figure for its age, translating to roughly 3,213 miles per year—a rate far below typical daily driving patterns. This low usage profile combined with the lengthy gap since the last MOT strongly suggests the car has spent considerable time idle or parked, which aligns with the poor condition of several systems. The tyre advisories recorded from 2014 through 2016, where both front and rear tyres were repeatedly flagged as worn close to legal limits, further supports a pattern of infrequent use where tyre wear accumulates slowly but consistently. The combination of minimal mileage and neglected servicing creates a scenario where lubricants have become contaminated, seals have degraded, and components have not undergone proper inspection cycles. The front brake disc remains a primary concern given its documented weakening in 2013 and continued presence of an oil leak at the 2023 test. On a test drive, the driver should monitor for any pulling to one side when descending hills, as a compromised disc can cause uneven pad contact and reduced braking performance. The exhaust system requires particular attention due to the major leak identified in both 2013 and 2023; listening for hissing noises around the manifold area and checking for smoke or odour during acceleration will help confirm whether the repair has been adequately addressed. Additionally, the brake pipe corrosion noted in 2023 warrants verification that the entire braking line has been inspected for internal damage that could compromise hydraulic pressure. The windshield washer deficiency, though less immediately dangerous, should be confirmed by observing whether the washer reservoir actually dispenses fluid during operation. Given the history, buyers should treat the front brake disc as potentially unsafe until proven otherwise and arrange independent professional inspection of the brake system before committing. The repeated tyre warnings suggest that even with low mileage, the tyres have shown signs of accelerated wear possibly due to changes in driving conditions or improper inflation, so measuring tread depth and examining the sidewall for cracks or bulges is essential. The oil leak reported across multiple MOTs indicates possible internal engine contamination or a leaking sump gasket, and a full engine compartment inspection is required to rule out deeper internal issues. Finally, because the vehicle sat untested for nearly a decade before its last MOT, assuming the current state reflects normal aging is risky; the lack of recent testing means any hidden deterioration in suspension bushings, subframe integrity, or electrical systems could remain undetected until a physical examination reveals new concerns.
