Bit late for me to go outside fishing in the boot of the partners Arona but what the order said was
Factory Fitted Options FULL SIZE SPACE SAVER WHEEL WITH ALL TOOLS 165.83
(2018/19 price exc Vat... feels inline with the one quoted above, sort of)
It was a Seat supplied one from their West London operation run out of Seat UK, as an adjunct so they picked it up as that on the ordering system. 2018/19. They kept the puncture repair kit. Swap out at delivery.
Also look at the Seat parts sponsor here or your
Seat dealer. You don't have to scrap around now looking although you can.
Initially what happened with these cars you had to pick up wheels off other models, Leon for the
Ateca etc. They changed that and Seat started selling them where people didn't want a puncture repair kit. The wheel size can be down to what's fitted 19->18" etc (my
Ateca one), not an issue.
I recall that's a full size one on the Arona, not a skinny, unlike mine.
