About the 1991 CITROEN AX

The 1991 CITROEN AX is a city car with a 954cc petrol engine. 49 of these vehicles were MOT tested in 2026, making it a rare model on UK roads. It ranks in the top 11% of all 1991 cars for reliability.

With an average of 75,954 miles at 35 years old, CITROEN AX owners tend to use this car less than the typical driver. Very low mileage could mean the car has been garaged or used only for short trips, which can cause its own issues like battery drain and moisture buildup.

1991 CITROEN AX Fuel Costs

The modest 954cc petrol engine keeps fuel costs low, which is a real advantage for a city car. Expect around 50 mpg in mixed driving, which works out to roughly £955 per year at current petrol prices of 142p per litre (based on 7,400 miles per year).

What does it cost to own a 1991 CITROEN AX?

Total estimated annual running cost is £1,230 (£103/month), broken down as £955 fuel, £20 road tax, £55 MOT, and £200 predicted repairs. The low repair estimate reflects the excellent 92% pass rate. These cars rarely fail their MOT, so unexpected bills are less likely.

Buying a Used 1991 CITROEN AX

At 35 years old, the CITROEN AX is firmly in budget territory. Purchase prices are low, but check for rust, worn suspension bushes, and electrical gremlins. A full service history is especially valuable at this age. If you're flexible on year, the 1990 model has the highest pass rate at 88%. Note: with only 49 tests in our data, these figures should be treated as indicative rather than definitive.

Common Issues to Watch For

Based on the 1991 CITROEN AX's fuel type, age, and engine size, these are the most likely problem areas to check.

Coil Pack Failure

Medium risk

Smaller petrol engines are prone to ignition coil failures, causing misfires and rough running. Replacement is £50-£150 per coil.

Rust and Corrosion

Watch out

At 10+ years, check wheel arches, sills, subframe, and brake lines for rust. Structural corrosion is an MOT failure. Prevention is far cheaper than repair.

Suspension Bushings

Watch out

Rubber suspension bushes harden and crack with age, causing knocking noises and vague handling. A full refresh costs £300-£800 depending on the car.

Service History

Low risk

Always request a full service history. Regular servicing is the single best indicator of how well a car has been maintained, regardless of mileage.
