About the 1999 Fiat 126
The 1999 Fiat 126 is a city car. Our records list a 652cc petrol engine, though engines vary between versions. 31 MOT tests were recorded on this model in 2024, making it a rare model on UK roads. It sits in the bottom 4% of 1999 models for MOT pass rate.
With an average of 51,308 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.
1999 Fiat 126 Fuel Costs
The modest 652cc 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 1999 Fiat 126?
Total estimated annual running cost is £2,160 (£180/month), broken down as £1,175 fuel, £230 road tax, £55 MOT, and £700 predicted repairs. The higher repair estimate reflects the 61% MOT pass rate. Cars in this bracket tend to need work on suspension, brakes, and emissions components.
Buying a Used 1999 Fiat 126
At 27 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 31 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 riskSmaller petrol engines are prone to ignition coil failures, causing misfires and rough running. Replacement is £50-£150 per coil.
Rust and Corrosion
Watch outAt 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 outRubber suspension bushes harden and crack with age, causing knocking noises and vague handling. A full refresh costs £300-£800 depending on the car.
Higher Than Average Failure Rate
Watch outWith a 61% MOT pass rate, this model fails more often than most. Budget for unexpected repairs and get a thorough pre-purchase inspection.
Service History
Low riskAlways request a full service history. Regular servicing is the single best indicator of how well a car has been maintained, regardless of mileage.
