Its a fun car, outclassed by many other hot hatches in the handling stakes, Fiesta ST springs to mind or Renault Clio but it absolutely dishes out character and soul in handfuls. It is pretty rapid too but it has got 200HP and I think they weigh 1070kg, but what I will say the ones I drove with the electronic diff (brakes a wheel) felt very odd at the limit, whereas the Performance Pack car, has a mechanical LSD and just revels to be driven beyond its limits and thus makes it a lot of fun and the engine is old school, lag lag lag, BOOOOOOST! Brakes are great but do not invite confidence as under heavy braking the back-end goes extremely light so braking from high speeds don't feel great.
End of the day the Abarth is based on a Fiat 500, a city car, Abarth did I feel best they could, the Comp is a fun car, but if you want handling, balance and lap times, look elsewhere, but if that don't interest you and you want fun, giggles and something that looks smart and comes from Abarth spot on pretty much look for a Competizione with Performance Pack or alternatively buy a base 145/160, fit an LSD and map it to 170-200HP depending on what turbo comes with car.
