About the 1990 Fiat 126

The 1990 Fiat 126 is a city car. Our records list a 704cc petrol engine, though engines vary between versions. 94 MOT tests were recorded on this model in 2024, making it a rare model on UK roads. It sits in the bottom 16% of 1990 models for MOT pass rate.

With an average of 31,887 miles recorded at its 2024 MOT tests, Fiat 126 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.

1990 Fiat 126 Fuel Costs

The modest 704cc 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 £1,175 per year with petrol at 174.57p per litre (GOV.UK weekly average, week of 19 October 2026; based on 7,400 miles per year).

What does it cost to own a 1990 Fiat 126?

Total estimated annual running cost is £1,960 (£163/month), broken down as £1,175 fuel, £230 road tax, £55 MOT, and £500 predicted repairs. Repair costs are moderate, reflecting the 71% pass rate. Keeping on top of servicing will help avoid surprises.

Buying a Used 1990 Fiat 126

At 36 years old, the Fiat 126 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. Note: with only 94 tests in our data, these figures should be treated as indicative rather than definitive.

Common Issues to Watch For

These are typical issues for cars of this age, fuel type and engine size, not faults recorded on this model's MOT tests. Use them as a checklist when you view one.

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.
