Also just got a sporting kit on and its listed as an HGT.
A lot of people do buy silly wheels and sell the standards when they have cars like this and then put some cheap steelies on when they sell it because they keep their new wheels for their new car. But why would the front bumper be changed? Accident damaged or an incorrect listing.
Edit: Autotrader reg checker lists it as:
Vehicle Registration Mark: MA03NLU
Make: FIAT
Model: PUNTO HGT 16V
Transmission & fuel type: MANUAL 5 GEARS PETROL
Body Type: 3 DOOR HATCHBACK
Colour: BLACK
