Would imagine the mirror caps,
CUPRA characters on the boot and front grille would be fairly easy to do (and reverse if you get bored of it or it goes wrong) but the wheels would be easier to refurb by a pro.
Haven't seen one with the orange line kit in the flesh but I've seen a Nevada White and orange pack example on the SEAT website and it did look nice. The old boy's gone for black with the Multi Spoke's for his
290 - think it would attract too much attention and I do like the stealthy look of the black ones... much more fun when whatever's on your back bumper tries to keep up with a '1.4 FR'...
