One of the cheapest cars in Britain to run — check the clutch and the rust.
Common Faults
Each fault below is drawn from real owner reports and UK garage patterns for this generation — not generic used-car advice.
Clutch and gearbox wear on high-mileage town cars
moderateAygos live in cities, so clutches get hammered. A high biting point or juddering take-off means it is near the end.
Check for: Pull away in second from stationary — if it creeps rather than stalls, the clutch is slipping.
Typical cost: £450–£700 fitted
Rear beam and sill corrosion
seriousOlder Mk1s rot around the rear axle beam mounts and inner sills, which is an MOT structural failure rather than an advisory.
Check for: Look under the rear arches with a torch; check the last three MOTs for any 'corrosion' wording.
Typical cost: £300–£900 welding, often more than the car is worth
MMT automated manual jerkiness
moderateThe single-clutch MMT semi-auto lurches between shifts. Normal for the box, but the actuator can fail.
Check for: Test drive it in traffic. Any warning light or refusal to select a gear means walk away.
Typical cost: £700+ for an actuator

Sharp questions to ask the seller
