Here's a lovely Citroen C1 i VTR, a petrol-powered car that was first registered in 2012. This VTR trim edition has had only two owners from new. The 1.0-litre engine is paired with air conditioning, including air conditioning, for those hot summer days. This C1 really shines when it comes to running costs. The fuel economy is excellent at 66 miles per gallon, meaning fewer trips to the petrol station and more money in your pocket. Furthermore, with CO2 emissions of just 99 grams per kilometre, you can rest assured that you're doing your bit for the environment while saving on road tax.
