2017 Fiat 500 1.2L Petrol · RO17 XMV

The most recent MOT test on 19 June 2026 resulted in a pass, following an initial failure on 18 June 2026 that was rectified at the same station within a day. The earlier failure cited the nearside and offside front brake discs as significantly and obviously worn, which is a major defect category under section 1.1.14 (a) (i) and would have required replacement before a pass could be issued. Both the 2026 pass and failure carry an advisory for rear sub-frame corrosion, noted as not seriously weakened under section 5.3.3 (b) (i). Looking at the broader MOT history, the trend shows a gradual accumulation of advisories from 2022 onwards, beginning with front tyre wear, progressing to inner brake disc pitting in 2025, and culminating in the brake disc replacement requirement in 2026. This pattern is consistent with progressive wear on a vehicle of this age, and while the current pass is clean of immediate defects beyond the sub-frame advisory, the rate of advisory accumulation suggests closer scrutiny is warranted. The recorded mileage of 21,348 miles over approximately nine years equates to an annual average of around 2,372 miles, which is substantially below the typical mileage for a vehicle of this age. This low usage figure raises the likelihood of extended periods of standing, during which certain components deteriorate through calendar age rather than wear. The MOT history shows annual testing since 2020 with no recorded mileage progression provided between tests in the data supplied, which can sometimes mask gaps in usage or periods of inactivity. Lower annual mileage generally preserves internal drivetrain components such as the engine and transmission, but accelerates degradation in items exposed to atmospheric conditions, moisture ingress, and lack of use, including brake calipers, brake discs, suspension bushes, exhaust systems, and battery health. The fact that brake discs have required attention despite low mileage supports the standing-vehicle degradation pattern. For a prospective buyer, the rear sub-frame corrosion advisory should be inspected physically, as corrosion in this area can progress over time, particularly given evidence of standing exposed to the elements. On a test drive, listen for any suspension clonks or knocking noises over uneven road surfaces, which could indicate worn bushes or top mount deterioration consistent with low-use standing. Examine the underside of the vehicle for any fresh underseal applied shortly before sale, which may be concealing active corrosion, and consider a structural inspection to assess the advisory area. The recent front brake disc replacement is a positive sign, but verify the work via invoice and confirm whether pads were renewed concurrently, as discs and pads typically wear in tandem. On test drive, check for brake shudder under firm application, pulling to one side under braking, or any grinding noises that might suggest incomplete rectification or a binding caliper resulting from lack of use. Given the low annual mileage, additional checks should include a thorough inspection of the tyres for sidewall cracking and perishing due to age rather than tread wear, despite the front tyres having been replaced within the MOT cycle. Inspect the rear tyres similarly for age-related deterioration. Test the 12V battery under load, as batteries deteriorate through standing and age regardless of mileage, and verify the manufacturing date stamp. Check all fluid services by date rather than mileage, particularly brake fluid which typically requires replacement every two to three years due to hygroscopic moisture absorption, and engine coolant and oil which should be verified for recent renewal. Confirm the service book stamping history and verify that cambelt or timing chain service intervals have been observed by time rather than mileage, as Fiat 500 age-related schedules may be approaching. Finally, on cold start listen for any timing chain rattle, and verify that the handbrake releases fully without binding, as handbrake cables and calipers can seize from prolonged standing.
