I'm in a similar situation. EDD is 19/6 to 30/6 (Brisbane). Hope to get it on or after 1 July to avoid the LCT as I ordered the 20" induction wheel. That's a saving of $355 based on my final invoice.
I haven't requested delivery in July yet, as the actual delivery date could be delayed to July. However, if my car is ready for pickup in June, I wonder if we can still request to postpone the delivery date. As I read in the Order Agreement, it says " You agree to schedule and take delivery of your Vehicle within one week of this date." I hope this means, as long as our actual delivery date is on or after 24 June, we could postpone it to 1 July. What do you think?
