Faults:

Premature water pump failure, requiring frequent checks of the antifreeze level to prevent overheating.

Inside the cabin, the plastics are hard and produce noises or rattles.

Dashboard warning lights turning on for no valid reason.

General Comments:

Despite some electronic issues common to cars of that era, the C1 is an ultra-compact city car, highly agile and economical, that is ideal for daily city driving.

A simple, no-frills compact car that, at 3.46 meters in length, offers urban mobility with an interior that is more spacious than it might appear. It is worth noting that this C1 shares many components with a natural sibling like the Peugeot 108 (from the same parent company) and another, more surprising and distinctive model: the Toyota Aygo.

It is obvious that a car measuring less than three and a half meters cannot offer a particularly spacious interior; therefore, making the most of the available space is crucial, especially for a vehicle that needs to serve a practical purpose for its owners.

The climate control area also features a distinctive trapezoidal design, with a central temperature display surrounded by the system's control buttons. The front seats are comfortable and offer a slightly body-hugging shape for support in corners; however, the fixed headrests somewhat compromise comfort for drivers of non-standard height.

The lack of an armrest near the gear shift makes long journeys somewhat uncomfortable, though this is a common shortcoming in cars of this size. The rear accommodates only two passengers, and the seat cushion is rather firm, while the backrest lacks sufficient padding for optimal comfort. Adjustable headrests are provided in the back, although limited headroom restricts the ability to accommodate taller passengers.

Once behind the wheel and the engine started, you are immediately greeted by the unmistakable sound of the one-liter, three-cylinder engine. You wouldn't expect exceptional soundproofing in a car of this size, yet noise doesn't intrude too much into the cabin of the C1. The little Citroën’s 72 horsepower are honest but don't offer much in the way of thrills; however, the car proves agile enough for city driving, even with four passengers on board, without suffering too much of a performance penalty. Fuel consumption is, naturally, extremely low, around 3 l/100 km.

This C1 keeps the spirit of the 2CV alive; it is a simply conceived car designed for practicality, featuring a playful style and design, adapted, in this instance, to modern times. Its main limitations stem from its size, which offers little in the way of spaciousness or cargo capacity, and the fact that the 72-horsepower three-cylinder gasoline engine feels somewhat underpowered.

In any case, it is a stylish, comfortable car with adequate performance.
