How many Citroen C4 Cactus cars are still on the road?

The Department for Transport's vehicle licensing statistics (DfT/DVLA table VEH0124) do not record the C4 Cactus under a name of its own: its cars are counted inside the C4 figures, so no separate count of taxed or SORN C4 Cactus cars can be given here.

Better or worse than the average car?

The C4 Cactus's pass rate minus the all-cars pass rate at each age, in percentage points. Bars above zero: the C4 Cactus beats the average car of that age. Below zero: it trails.

Petrol, diesel or hybrid C4 Cactus?

What mileage is normal for a C4 Cactus?

Mileage recorded at test by vehicle age, 2025. The line is the typical (median) C4 Cactus; the shaded band holds the middle half. A car far outside the band, in either direction, is worth questions the recorded history can answer.

How these figures are computed. Every number on this page is calculated by SortedCars from the DVSA anonymised MOT results dataset (every MOT test in Great Britain — 2025 for single-year figures; trend figures state their span, currently 2023–2025). Where a figure comes from a sample or uses banded values (mileage is banded to 2,500 miles), the page says so beside the figure. Test class 4 only, first tests only — retests are excluded. Class 4 is the car MOT class and also covers car-derived vans, pickups and motorhomes tested to the same standard; where this page says "cars" it means class 4. Pass rate = passes ÷ (passes + failures + pass-after-rectification): a vehicle that failed and was fixed during the visit counts as a fail. Pass rates describe fleets, not individual machines: they reflect how cars were driven, maintained and used as well as how they were built, and beyond recorded mileage none of that is in the data. A well-kept example of a model with a weak average can still pass; a neglected example of a strong one can still fail. No figure is shown for any group with fewer than 500 tests. Alias spellings of a make in the DVSA file are counted under one make name, and all trims and variants of a model are grouped under one model name, using SortedCars' grouping tables. “Dangerous” is DVSA's statutory defect category (in force since May 2018): a defect posing an immediate risk to road safety — driving the vehicle before repair is an offence. What these figures are for. These statistics are general information about groups of vehicles. They are not advice, a valuation or a recommendation to buy, avoid or price any particular vehicle, and no decision about one car should rest on them alone — check the car itself and its own records. We take care over the calculations, but we cannot guarantee they are complete, current or free of error, and we accept no liability for loss arising from reliance on them. This does not limit any liability that cannot lawfully be limited — see our Terms & Conditions. If you believe any figure on this page is inaccurate, contact us.
