Two I've seen in person at dealers are not as are some pre-reg currently advertised. Hence the question.
If it’s a CUPRA R ST that’s pre registered and not ABT then I’d suggest discussing with the dealer who has it. As @Damo H says most will already have the ABT pack (why wouldn’t they fit an extra £500).
I know that the dealer has to supply Seat UK and ABT with details of the car and to confirm it is an R ST so it may be possible (unless there’s a clause saying it must be fitted prior to registering).
