This is the best part of integirity in FIAT owner's even a small problem is discussed in detail here: Anyways, I own 2 Punto's: 1st (done 45000Kms) is of June 2010 made and 2nd (done 15000 Kms) is Dec 2011. What I can say about this probelm is that its not a manufacturing defect because I cannot see this in my new second punto. But in my first punto 2 years old now, I can see 3 bulge as mentioned below but I doubt that it is due to below two reasons my car had undergone at Delhi roads: 1. People don't use hand breaks while stopping in traffic jams at slops and innocently hit the back car badly. I hate these lazy people for god's sake hand brake should be used anyways it is not eating up extra fuel. My 1st car has been thrashed twice like this by 2 idiots. 2. Once, I was sandwitched between a series of 10 cars hitting on road by sudden braking and I was in between but I thanked the hard material used by FIAT here becuase nothing was damaged from front and back. I doubt that these events developed these bulgs in my car but cannot be sure on this but can only think this way because closing the bonnet cannot be issue with the kind of sheet used in FIAT. Will post the pics soon.
