Came away thinking it was a perfectly good warm hatch. Performance maybe a little more refined than I was expecting.
Cabin felt a little small, seat could have gone a bit further back and not that much headroom (189cm).
You certainly didn't have to thrash it to get decent performance out of it.
We aren't looking for an out and out banzai hot hatch, just one with more performance than your every day 75bhp asthmatic hatch.
As for B roads, I'm sure it would be more than capable.
Out of the two I prefer the Abarth 500, it's a fair bit cheaper, little better performance, less refinement, better looks. Can live with a smaller boot as the cabin space is fine and just put th seats down.
