I have driven a Fiat 500 as a rental car (not Abarth).
Good car, it has more storage capacity than you would think. When I was driving it I hit a small bump in the road and my 4-way flashers came on and would not turn off, even if I turned the car off. I tried rummaging around under the hood and under the dash and could not get them to turn off (it was pitch black out... so this didn't help).
I drove back home and they eventually turned off on the way home, but then came back on again.
I took some of the panels off to get at the relay/fuse box below the steering wheel and found that one relay seemed to be loose. I just pushed everything back in rather hard and it didn't happen again.
Hopefully you don't like doing your own maintenance/work on your vehicle as that engine bay is EXTREMELY tight.
I would love to try the Abarth, the regular 500 with an auto was by no means slow... so I imagine a manual with a turbo would be quite quick.
