The problems I experienced are such a shame, because the Seicento should be a brilliant car - it's got real character. The design is great, the execution isn't.
Great handling - leagues ahead of standard version (front anti-roll bar makes a huge difference).
Fairly good MPG - usually around 43mpg.
Probably one the fastest cars with a 1.1 engine - especially if revved quite hard. Very smooth engine (sounded good too, even with standard exhaust!) - easily capable of 100mph. Pulled better from 80-100 than it did from 50-70!
Even though it's supposed to be a town car - I always found it far better out of town, on a back road with lots of bends! The radiator is too small for town use - the cooling fan constantly went on and off in traffic.
Very good seats, albeit the driving position was slightly offset.
Interior lasted well - funky design with fantastic rev counter on top of dash.
Good sounding Sony CD player as standard.
A characterful, fun car, let down by dodgy build, poor dealers and couldn't-care-less importer. Quite tragic really.
