I note that on the Land Rover Australia web site it now says:

Defender 90 production and first customer deliveries have been delayed for reasons beyond our control. We anticipate Defender 90 will be available to order from September 2020. Defender 110 is available to order now.

I am interested in the 90 as the 110 is bigger than what I need/want, so I will just wait patiently - only another month to go by the sounds of it...

Cheers,
GG.
