If it helps, this is what happened in my case:
- I ordered on 2nd of June via Leasing Options, as a custom order, not part of any pre-ordered batch
- was originally told October delivery
- confirmed build week of 36
- in week 38 I found out that it did not happen
- in week 42 was told car is expected at the dealer in December
- in week 43 (this week) I was told its actually at the UK port
- hours later I got a call that its at the dealer and its time to sign papers
- looking for delivery in November
An overall bit confusing process, but pretty much on time.
I have to say that Leasing Options and Cupra UK did their best to keep me informed, and were very pleasant. It's just a shame that Cupra UK no longer provides updates via chat. It just shows how chaotic ordering a new car is these days.
