5 owners in 6/7years is a lot, and the mileage is very low...almost too low; creating extra owners is a car dealer trick when clocking a motor; if the history is 'independant' I'd be very wary.
I'd be very carefull - it's worth checking with FIAT as to what FIAT service history it has and any warranty work - incase it's a bit of a lemon / friday afternoon car.
