2010 Smart Fortwo Cabriolet 1.0L Petrol · E4 PJR

The most recent MOT, carried out on 5 March 2026, was a pass but it was accompanied by two advisories: both rear tyres are showing cracking indicative of perishing, and both rear exhaust mountings are deemed defective. Over the preceding five years the vehicle has alternated between passes and a handful of failures, the latter primarily relating to lighting faults and front suspension bush wear. Although the failures have been remedied sufficiently to achieve subsequent passes, the recurrence of tyre perishing, exhaust‑mount deterioration and suspension‑bush wear suggests a maintenance pattern that is not improving and may be edging towards a more reactive than preventative approach. With 70,435 mi recorded on a 2010‑model Smart Fortwo Cabriolet, the average annual mileage works out at roughly 4,400 mi. This is well below the typical UK average for a vehicle of this age and points to either a very gentle usage profile or extended periods of inactivity. Low utilisation reduces mechanical wear on the power‑train but accelerates age‑related decay of rubber compounds, battery plates and metal components; consequently, the vehicle is more likely to exhibit perished tyres, a weakened battery, and corrosion on suspension joints and under‑tray areas than a similarly aged car with higher mileage. A prospective buyer should give particular attention to the rear tyre condition. Examine the tread depth on both rear wheels, check the sidewalls for dry‑rot, cracking or any bulging, and verify the DOT code to confirm the tyres are not beyond ten years of service. During a road test, listen for any rattling or low‑frequency vibration emanating from the rear exhaust system, which would confirm the defective mountings and could indicate a risk of exhaust leakage or increased cabin noise. Inspect the front suspension arm pins and anti‑roll‑bar linkage for excessive play by applying firm pressure to the wheel at the 12 o’clock and 6 o’clock positions; any clunk or noticeable movement would corroborate the previous advisory on worn bushings and may necessitate replacement to avoid premature tyre wear or compromised handling. Beyond the identified issues, verify that all lighting functions operate correctly, especially the near‑side stop lamp and both side repeaters, and confirm that headlamp aim is within legal limits. Check the condition of the battery, looking for swollen cells, corroded terminals and measuring voltage after a short idle; a battery approaching ten years of age should be tested under load. Inspect the brake discs for surface rust, scoring or uneven pad wear, and ensure the calipers move freely without binding. Finally, confirm that the engine oil, coolant and brake fluid have been changed within the recommended intervals, as fluid degradation over time can lead to reduced lubrication, overheating or compromised braking performance even on a low‑mileage vehicle. A thorough visual inspection of the chassis for rust, especially around the under‑tray and exhaust mounting points, will help assess whether prolonged standing has introduced structural corrosion that could affect long‑term reliability.
