I have the 45kw Style in Glacier White, being handed over in 3 weeks time. I only commute a 100 miles per week, so had no need for a bigger battery.
BP installed my home charger within 2 weeks, of completing the online paperwork. Looking at other reviews I appear to be fortunate!
I am on a forum on Facebook for the ID.3 and 20 weeks seems about right for delivery, if the wind is blowing in the right direction:)
