I ordered one yesterday and was told 2 to 3 months delivery time from the factory. But it didn't sound very convincing, it was more like they quoted me a standard lead time, not Z specific. So I will call them regularly to check...
The problem for us in the states is that the Z is being introduced around Europe at this time as well, so I assume this will limit the propduction capacity for US spec cars. On the other hand, they are in crisis as well, so hopefully there will not be too many buyers out there
