That answer I am happy with - but as you say, they should be telling us without us having to pester.
I don't know what everyone else thinks, but I feel like a nuisance phoning up asking for updates, it shouldn't really be like that.
Also, while ever there aren't real updates, speculation of all kinds will run out out of control and we will naturally begin to lose faith in our vehicles before they have even been delivered. Reliability and 'fit for purpose' should be demonstrable from the moment of order and the transaction of a deposit.
