What alternatives should I consider to a used Citroën C1 hatchback?
If you want the most dependable car in the city car class, look for an Aygo. Since it's basically the same car as the C1 underneath, you get the same fuel economy and performance, but it came with a five-year warranty rather than the three years Citroën when it was new, which means there might be some cover left on the Aygo whereas it could have run out on a C1 of similar age.
The i10 is a firm favourite of ours, thanks to its spacious interior, decent standard kit and surprisingly good refinement. It too comes with a lengthy warranty.
