You do get missbuilds. The question is whether all of the UK models had it missing. Seat / Cupra often say the advertised spec may vary. The UK branch passes onto the factory the car to be built in the range. My belief they don't have good QA on the advertised spec and what the factory builds. In my case Seat UK knew they had misbuilt mine. No wireless charger. In Europe at the time they were selling
Ateca Xcellences without wireless chargers with the mib2 plus model. So I got a righthand drive model of it. There were other people in the UK like it. Seat were good enough to phone up and say your car has been misbuilt. I entered negotiations to get recompense for their error, given I'd paid for it. Three years free service but didn't give a good experience. Rushed on pick up days as I held out.
Seat / Cupra UK should go over the intended build spec with what they gave the factory before the car gets built (production). Evidently they don't always, so you end up with a car built for a different market albeit righthand drive. In this case it was the factories fault but you'd expect the UK office would go over what the factory intended to build. It's the build codes, it's easy enough.
