You can only buy Inventory from your home state , Tesla won’t transfer them.Well there is still a chance that a RWD car ultimately destined for you has been made but not shipped yet. It seems the VIns are assigned when the ships are on the water and close to port. We have no idea (noone does) on RHD production numbers let alone by your variant and destination (Sydney). Nor do we know how many RWD customers are in front of you in your particular queue (again not just date&time of order but also variant and destination). That report did say that they have large stocks produced still to be assigned to ships and despatched so you probably won't know until late March or April whether there is a chance of getting one by end of May, or whether your dates move to Apr-Jun which seems to be the next window. If a lot of peoples dates start moving on here then that is an indication that the Quarterly production for us has run out. Of course the current shipping delays at Oz ports looks likely to add at least a month to many deliveries and it seems to be getting worse not better, and these things are like traffic jams anywhere, they escalate.
I don't know but I suspect you could easily drop $10K on a buy then tradein, given Tesla themselves do not handle the secondhand cars, they go straight to resellers which is a very "sharp" business with relatively large margins. No one (let alone Tesla Australia) will do you a favour. You'd surely be better off selling privately to someone looking for an M3 who also doesn't want to wait. Spending three or four grand on keeping your current car going is possibly another option? e.g. replacement drivetrain from a wrecker.
Maybe keep a very sharp eye on Telsa MY inventory around Australia, there are likely to be a few Y RWDs pop up towards the end of the quarterly production run (quite a few M3's have) and it would be far cheaper to snap one up and then ship it home than drop the $$$$ on a secondhand one. These would be from people getting cold feet at the time of settlement, bought something else, etc. WA may be the best bet as they seem to get the best stocks.
This is all just my uniformed but interested opinion. Our 15 year old Golf is also on its last legs, just hoping it hangs in for a few more months.
Cheers
But it is one of the best ways to avoid the longggggg wait .
