2016 Fiat 500 1.2L Petrol · WP16 KWW

With a decade of recorded mileage sitting at 45,399 and an annual accumulation rate of roughly 4,540 miles, this Fiat 500 presents an unusual usage profile that warrants careful mechanical scrutiny. The November 2025 pass at this odometer reading is encouraging on the surface, but the broader history shows a cluster of advisories concentrated in the late-2024 test that point to underbody wear typical of cars used primarily for short urban journeys. That 2024 examination recorded four separate advisories including exhaust corrosion, inner-edge front tyre wear, suspension bushes, and a discoloured rear indicator, while the earlier 2023 retest following a major mirror failure passed without any further issues. The single failure was a relatively minor bodywork item rather than a structural or mechanical defect, which suggests the core drivetrain and running gear have remained roadworthy, though the 2024 advisory cluster indicates the supporting components are beginning to demand attention. Mechanically, low annual mileage on a 2016 Fiat 500 of this vintage creates specific concerns. Vehicles used predominantly for short trips rarely achieve full operating temperature, which accelerates corrosion on ferrous underbody components and promotes moisture retention in the exhaust system, consistent with the corroding exhaust advisory noted in 2024. Equally, the nearside and offside front lower suspension arm rear mounting bushes flagged as worn in that same test are precisely the components that suffer when a car is driven over worn urban road surfaces with light loads. The inner-edge front tyre wear pattern noted in 2024 is also characteristic of geometry issues stemming from those compromised bushes, and the front brakes, while not yet flagged, will have accumulated moisture and surface corrosion due to the limited sustained use. Although the 2023 December test passed cleanly, and the 2022 test was similarly unblemished, the pattern of zero advisories followed by four in a single year is worth weighing against the modest mileage accumulation. A prospective buyer should focus the pre-purchase inspection on the lower suspension arms and their rear mounting bushes, as these were flagged on both sides in 2024 and have likely deteriorated further over the intervening twelve months. Listen for clonking noises from the front end over speed bumps and uneven surfaces, and feel for imprecise steering response or vague cornering behaviour that would indicate the bushes have worn beyond the advisory threshold. Inspect the exhaust system from the catalytic converter rearward for the corrosion that was already progressing in 2024, paying particular attention to mounting brackets and the rear silencer joint. The front tyres should be checked for uneven inner-edge wear which, if present, would confirm the suspension geometry has shifted, and the nearside front door mirror should be verified as a genuine unit rather than the damaged original that caused the 2023 failure. Given the very low annual mileage, the engine and gearbox are unlikely to have suffered major wear, but components that degrade with age rather than use demand close attention. Check for oil seepage from the cam cover gasket, coolant leaks from the thermostat housing area common on FireFly-era Fiat engines, and condition of the auxiliary drive belt. Inspect the rear brake calipers for seizing, as these can bind when a car is used infrequently, and examine the rear discs for severe surface corrosion that may now exceed serviceable thickness. Verify that the rear direction indicator lens has been replaced and remains clean, as the 2024 advisory for discolouration can quickly become a fail if the lens cracks or fades further. Finally, a thorough road test should include a cold start to assess for excessive smoke or rough idle, and a steady motorway run to confirm the cooling system functions correctly, which is particularly important for a low-mileage car that may not have been subjected to sustained loading in recent years.
