I have had no real problem's with the Fiat Cinquecento Sporting since I have owned it, the only thing I could comment on is:
My Lamber Sensor went a few week's after I got the car which cost £130 to have fixed.
Driver seat position adjustment bar snapped costing £40 to have repaired.
Since I got this car I have added a Novitec Cinquecento 1.1 74 kW (118 hp) Turbo kit and its hard to explain the difference in Performance.
I get about 0 - 60 in 7.1 seconds unlike the standard speed of 11 seconds this is a massive increase in power.
I've also added new Apex -40mm Suspension Kit and it now holds the road like "it's on rails" but I must point out the standard Sporting Suspension is also very good.
The Sporting model comes with Red Seat Belts and some very sporty seats that are still used in the Seicento Sporting.
The overall interior is maybe a little basic of features such as Air Reconditioning, but it does come with Electric Windows, but the switches are in a bad position.
Hi mate, can send me a picture of your car?
Can you tell me where you got the turbo kit and how much it cost? I'm thinking about getting one of these.
