Donald -- sorry I'm behind, but I'm currently traveling and more out-of-touch than usual! 😉
Welcome to MV! Great folks, even better advice. And we do love pictures!
I've been fortunate enough to spend quality time in Australia on several occasions. I've even considered relocating to either Sydney or to Fremantle, quite a lovely town!
You'll really dig your Vespa. If you're like me, though, you'll end up adding to your collection. I currently only have 2 -- a '24 GTS 300 base model and an '01 ET2 I'm hoping to "hot rod" over the fall/winter. I've started looking for a PX 200 to keep the other two company.
Where you are, you should be riding the wheels off that 150 of yours. I've added pics of my 2 to encourage you to post a few of your own.
Cheers!
Victor
