I absolutely love this car, we just swapped our peugeot 106 for a black Mini One. It handles great, looks great and has a fantastic sound system - a million times better than the Pug and holds value incredibily well.
Nice looking with bags of charm. It drives really well too, but rear passengers will find it too cramped. It may be quite nippy but, my concern is that the engine is a Brazilian. Still, they seem to be reliable and have more character than any other car. They have high residual values, but they are not excalty cheap to begin with. Still, remember you are buying an iconic car.
