About the 2018 FIAT SUNLIGHT
The 2018 FIAT SUNLIGHT is a family car with a 1956cc diesel engine. 142 of these vehicles were MOT tested in 2024, making it a rare model on UK roads. Among all cars from 2018, the average MOT pass rate is 89%, and this model beats that benchmark.
With an average of 21,887 miles at 6 years old, FIAT SUNLIGHT 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.

The 1956cc diesel engine offers a reasonable balance between performance and economy. Expect around 48 mpg in mixed driving, which works out to roughly £1,037 per year at current diesel prices of 148p per litre (based on 7,400 miles per year). Diesel cars of this age should have their DPF (diesel particulate filter) checked, as replacements can be costly.
