2018 Fiat 500 1.2L Petrol · RO18 ETV

The 2018 FIAT 500 presents a generally sound mechanical picture, though the most recent MOT on 2020-01-20 at 39,804 miles reveals a maintenance trend that is beginning to shift from stable to mildly concerning. The vehicle passed its latest test, but the tester flagged front brake discs worn, pitted, or scored, alongside a rear suspension arm noted as corroded on the axle. While neither defect was deemed serious enough to cause a failure, the combination of braking surface degradation and structural corrosion on a sub-40,000-mile car suggests the vehicle may have spent extended periods stationary, allowing moisture to attack components that regular use would typically keep clean. The 2025 test at 29,539 miles also recorded pitted and scored front brake discs on both sides, indicating this is a recurring issue rather than a one-off event. Brake disc pitting of this nature often points to prolonged standing or infrequent use, where pad-to-disc contact rusts the surface rather than wiping it clean. The mileage profile reinforces that suspicion. Between the March 2022 test at 15,946 miles and the March 2023 test at 18,706 miles, the car covered just 2,760 miles in twelve months. The following year, between March 2023 and February 2024, it added only 1,701 miles. Then, between February 2024 at 20,407 miles and January 2025 at 29,539 miles, the car suddenly accumulated 9,132 miles in under eleven months, a sharp acceleration. By January 2026, the odometer read 39,804 miles, meaning another 10,265 miles were covered in roughly twelve months. This pattern of long dormancy followed by intense use is consistent with a vehicle that changed hands or usage patterns around late 2024, and it explains why corrosion and brake disc pitting appeared despite the relatively low overall mileage. A buyer should inspect the front brake discs and pads in person, checking whether the pitting noted in both 2025 and 2026 has deepened to the point where the discs require replacement. The rear suspension arm corrosion flagged in the 2026 test warrants close examination with a torch and probe, particularly where the bush meets the arm, as Fiat 500 rear beam axles are known to corrode from the inside out. The inner edge tyre wear noted on both front tyres in 2025 suggests toe misalignment, so a four-wheel alignment check is advisable before committing to a purchase. Given the long periods of inactivity, the brake fluid should also be tested for moisture content, as standing fluid absorbs moisture and reduces boiling point without any visible sign.
