Nothing so far.
Good solid build quality, door shuts excellent.
Super seating, plenty of space for 5 adults (5 door model). "Tardis" like interior (bigger inside than it looks!).
Very quiet engine, but the 1.2 is not the fastest on acceleration.
Very economical.
Reasonable when climbing 1:4 hills (25% gradient).
Superb design inside and out.
Very simple mechanical layout.
Highly recommended!
Thank you for the good review.
