Check a specific Fiat Cinquecento SXShould you buy a used Fiat Cinquecento SX?
The Fiat Cinquecento SX has an overall MOT pass rate of 61.1% across 2,797 real MOT tests — below the UK average, so reliability should be a key concern.
The most common problems on the Fiat Cinquecento SX are parking brake: efficiency below requirements (407 recorded failures), parking brake recording little or no effort (230), and direction indicator incorrect colour (201). These are the faults most likely to cause an MOT failure on this model, so check for them carefully on any test drive or pre-purchase inspection. Many are wear-and-tear items that can be budgeted for, but a car that's already failing on multiple fronts may signal neglected maintenance.
A typical Fiat Cinquecento SX owner drives around 4,779 miles per year. If the car you're looking at is significantly above this, expect more wear on suspension, brakes and tyres. If it's well below, the vehicle may have been sitting unused — check for perished rubber, corroded discs and stale fluids.
In terms of longevity, most Fiat Cinquecento SX models stay on UK roads for around 31 years — a strong showing that suggests solid build quality and readily available parts. If you're buying one that's already approaching that window, the data suggests it has plenty of life left provided it's been maintained.
Before committing to a purchase, we recommend running a full vehicle history check on the specific car. This will reveal any outstanding finance, stolen markers, write-off history and mileage discrepancies that the seller may not disclose — and that the MOT data alone can't tell you.
