I've owned a current generation K13 for one year now. Before the K13 I owned a K12 1.6L, a K12 1.2L and a K11 1.3L.
Options: Keyless entry, engine start/stop button, climate control, rear parking sensors, parking slot measurement, navigation, rain sensing wipers, automatic headlamps, panoramic roof, folding heated sidemirrors, heated seats and special interior lighting (only with Ivory cloth).
Engine: It has a 1.2L 80bhp engine.
1.2L Fuel economy: Fuel consumption is about 6.1L/100km. I managed 4,3L/100km on cruise control on a 80km/h road.
Overall: The K13 is a great car. Small but not too small. Affordable when buying and very affordable in maintenance.
