It wouldn’t surprise me if loads of vehicles have a huge drop in AP for the Q2 list plus a load of additions of stuff not normally on the scheme, all while nobody can actually place an order. Once this virus problem starts to ease and hopefully by Q3 they will all disappear and the new stuff will not come back on, the vehicles that had reductions in AP will go for a short time and then come back on with massively inflated Advance Payments and very very long build times. I fear will will be last on the list when it comes to the manufacturers getting back up to speed and fulfilling orders, 3rd class citizen status all over again.
I would imagine there will be a massive problem with logistic and the supply chain and as you rightly point out very long build times.
Unfortunately I have suffered a brain injury and occasionally I get confused and often say the wrong thing.
