Great MPG, Cheap Tax, Recent Service and MOT - Great Car. With a fuel economy of 61 mpg, this Citroen DS3 excels in efficiency, meaning fewer trips to the petrol station and more money in your pocket compared to other similar vehicles. Low CO2 emissions mean that this car is kinder to the environment, and cheaper to tax than other similar vehicles. Selling on behalf of my mother as she now requires an automatic. Plenty of service history and receipts.
