all the parts are genuine seat items, i got them from the guy who used to be on this forum who was the parts guy for a seat dealer, which ment he offered a bit of a discount. All bar the front bumper that is, which is a replica from ebay (i wouldnt recommend it)
There are alot of parts to buy, to fit the rear bumper you need runners and clips etc, to fit the side skirts you need a whole host of brackets and clips and to fit the front bumper you need all of the above plus some grills etc. It does come to quite alot of money but its worth it (although i would say that!)
i had my parts sprayed together at a local bodyshop, borrowed my company van dropped off all the bits and picked them up a few days later. cant remember how much he charged me but it was a good price for cash (around £250 i think)
You should be able to find one bumper or the other on ebay in the correct colour, as you say i couldnt do that becasue mine didnt come in that colour in cupraR or MY03 cupra stance
