IF you look under the bonnet there is a sticker on the inside of the bonnet or bulkhead that says the paint code. If you give them the paint code could they spray it in advance of fitting it? To be honest €110 supplied fitted and sprayed is cheap, and I would be thinking that the paint job might not be great for that kind of money. I have an 03 punto which we have had from new and had a dint taken out the door and sprayed and it was €140 by the dentman.ie.
Take it to a couple of body shops and get some quotes. There are loads of second hand punto bumpers on ebay too. Might get a colour match there and get it Parcel Forced over.
