I've ordered my custom plates, and they are now sitting at the RMS waiting for my vehicle to arrive. I was so tempted to go with BMW F30 which I discovered was available but because it doesn't conform to one of the "standard" plate designs, I was going to have to cop $440 per year. In the end I settled on going with the number number-first plates and got 320 BMW which fits one of the new designs and only costs $99 per year.
It is annoying though because last time I got custom plates (for my early mid-life crisis car - a 300ZX) you didn't have to pay a yearly fee if you had one of the standard letter/number combinations, only an ordering fee. Now it seems that if you want any control over what is on your plates in NSW, they are going to charge you for it continuously.
