Oh dear.
To paraphrase from The Lion King
Ev - "Oww! Geez what was that for?"
Dave - "It doesn't matter! It's in the past! And you bought ANOTHER AU XR8 WHEN WILL YOU LEARN ERMAHGERD DO YOU EVEN EVAN"
Ev - "Yeah but it still butthurtz when I sell every 6 months"
Dave - "Ahh yes, but the way I see it, you can STICK WITH ONE AU AND LEARN FROM THE PAST."

To recap:
You spent fair coin on a dual fuel AUIII manual XR8 in good condition. LPG was a little dicky so you sold it for the same price you bought what's basically an AUIII Forte 4.0 stocker...
You've probably sold the SR at a loss and spent fair coin on another AUIII manual XR8.
You're back to where you were at with the previous AUIII manual XR8 but with no gas system, and thousands $$$ down the hole.
With all the transfer fees you must pay to VicRoads, they probably have set up a new ticketing option: ARE YOU EVAN [YES/NO], and if you select YES you skip the line to pay your money even faster.
