About the 2017 FIAT 124
The 2017 FIAT 124 is a small family car with a 1368cc petrol engine. 1,559 of these vehicles were MOT tested in 2026, making it a reasonably common sight on UK roads. Among all cars from 2017, the average MOT pass rate is 87%, and this model beats that benchmark.
With an average of 30,222 miles at 9 years old, FIAT 124 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.
2017 FIAT 124 Fuel Costs
The 1368cc petrol engine offers a reasonable balance between performance and economy. Expect around 42 mpg in mixed driving, which works out to roughly £1,137 per year at current petrol prices of 142p per litre (based on 7,400 miles per year).
What does it cost to own a 2017 FIAT 124?
Total estimated annual running cost is £1,587 (£132/month), broken down as £1137 fuel, £195 road tax, £55 MOT, and £200 predicted repairs. The low repair estimate reflects the excellent 90% pass rate. These cars rarely fail their MOT, so unexpected bills are less likely.

Buying a Used 2017 FIAT 124
At 9 years old, this is a solid used buy if you find one with good service history. Depreciation has levelled off, so you won't lose much more value. Focus on condition over mileage. If you're flexible on year, the 2018 model has the highest pass rate at 91%.
Common Issues to Watch For
Based on the 2017 FIAT 124's fuel type, age, and engine size, these are the most likely problem areas to check.
Suspension Wear
Medium riskShock absorbers, springs, and anti-roll bar links typically need attention around this age. Listen for clunks over bumps and check for uneven tyre wear.
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.
