2003 Smart Roadster 80 Auto(rhd) 0.7L Petrol · YW03 TPV

The most recent MOT, dated 21 April 2026, recorded a pass after an earlier failure on the same day for non‑functioning stop lamps. The failure was remedied and the vehicle now meets the statutory requirements, although a number of advisories persist. Over the past three years the pattern shows a stable but slightly deteriorating condition: the oil‑leak advisory has been present since 2026, the brake‑hose deterioration has been noted annually, and minor corrosion on the sills was flagged in 2025. No new major faults have appeared, indicating that the vehicle’s overall maintenance has not regressed dramatically, but the recurring minor items warrant attention. At 79,897 mi recorded for a 2003 model, the average annual mileage works out at roughly 3,500 mi. This is considerably below the typical 10‑12 000 mi per year expected for a car of this age, suggesting long periods of low use or storage. Low utilisation reduces wear on engine and drivetrain components but accelerates age‑related decay of rubber, plastic and metal parts. Consequently, wear‑related items such as brake pads and tyres may be relatively fresh, whereas seals, hoses and battery components are likely to have suffered from calendar ageing rather than mileage. When inspecting the vehicle, give particular focus to the front and rear brake hoses that have been described as “slightly deteriorated” for several consecutive MOTs. Look for any external cracking, swelling or fluid seepage around the hose fittings, and listen for a soft hiss or feel for a spongy pedal under hard braking, which can indicate internal hose weakening. The oil‑leak advisory should be traced to its source – a common culprit on the Smart Roadster is a leaking valve cover gasket or oil separator – and any wet spots on the sump or under the engine bay should be examined for signs of progressive leakage. Verify that both stop lamps illuminate correctly and that the lamp housings are sealed against moisture, as previous major failures suggest a possible wiring or bulb socket issue that could re‑appear. Given the car’s age and low mileage, time‑based inspections are essential. Examine the tyre sidewalls for cracking, dry rot or hardening, even if the tread depth appears adequate, because rubber can perish after a decade regardless of use. Check the 12 V battery for sulphation and verify that it holds charge; a battery that has sat for long periods often requires replacement. Inspect the under‑carriage, sills and wheel arches for surface corrosion, especially around the areas previously noted, and ensure that any rust is superficial rather than structural. Finally, confirm that all fluid reservoirs – brake, clutch, coolant and power‑steering – contain clean, correctly coloured fluid and have been changed within the manufacturer’s recommended intervals, as fluids degrade with time even when the car is not driven heavily.
