The annual list, researched by JD Power based on customer satisfaction surveys, found the Fiat 500 was the second most reliable city car in the UK and the Fiat Panda was the fourth.
The survey took into account vehicle appeal, quality, reliability, ownership costs and the service from Fiat dealerships.
Unsurprisingly, the Fiat 500 was voted the most appealing out of all city cars, another accolade for a car once voted sexiest car on the market by BBC’s Top Gear.
"Owners rated the Fiat 500 as more appealing than any other city car available, especially because of its retro styling and impeccable driving manners," says JD Power.
Ownership costs have also received a boost in the Fiat 500 with the introduction of the two-cylinder petrol TwinAir engine.
The engine, which was named International Engine of the Year, lowers CO2 emissions beneath 100g/km for the first time on a petrol engine, making it eligible for free VED and congestion charge exemption in London.
In fourth place, the Fiat Panda moves down two places since last year, but the seven-year-old city car remains a popular choice for small car drivers.
JD Power says the Panda made the top five in the city car category because of its practicality and high quality of servicing from Fiat dealerships such as Perrys Fiat in Amersham, Aylesbury and Portsmouth.
Fiat has targeted improvements in the overall list and has moved up seven places in three years to 22nd place as it revamps its customer service.
"Clearly, there is a massive amount of work still to be done," says Andrew Humberstone, managing director, Fiat Group Automobiles UK. "However, the positive results of the task we initiated three years ago to improve customer satisfaction in Fiat and its products are starting to show through."
