107, C1, Aygo all the same car. Very cheap tax and insurance as they are cheap to fix, everything bolts on off I think. £35 tax for the 1.0.
My daughters run an Aygo for the last 5 years, quite a firm ride and watch out for clutches, they don't last too long. I think they have now been uprated. Hers lasted 28k...£600 bill! Other than that it's been bullet proof.
