Dont worry Tim. I bought new alloys for the wife's Punto. Nothing to it, jack it up, swop wheels, I thought something was odd as it took me ages to get them to fit and tighten up.
Got them on and looked good, wife went off down the road and I thought how good they looked. Just as she went left at the bottom of the hill, I heard a thunkkkkkkkkkkk.
5 mins later had a phone call, she had pulled off the main road and stopped down a side road, funny noise.
Anyway turns out the center hole changed on the newer Puntos, we had 59, new ones are 57, why they have to change things. Back on steels with the attractive plastic trims. Got two sets of alloys to sell back on ebay!!!!
