Build weeks seem quite random. I ordered an 80x sportline plus near the start of October. Some people have been quoted week 48 etc but I was told yesterday that mine is week 10 and I should receive it in April. That will be 6 months from ordering. I’m still waiting for the correct model to be updated on the Motability account.
In my opinion that sounds more like the dealer held off placing the order with Skoda until the 85 Motability pricing came through at the end of November/start of December – that would bring it in-line with the pretty standard 16-20 weeks lead time.
