it'll say Seatsport on the seats and not cupra
this is basically the only cupraR component which will tell u wot model it is
as the brembos, the wheels, the gauges in the cubby pot and the badges an engine cover can be bought fairly cheap to upgrade a normal cupra
may just find a past owner sold the superTs cos they are in great demand, bought some aftermarket alloys and then sold them and bought sold cupra rims off ebay when he was selling the car
