Umm, there's sometimes a meet held at Independent Motorsports on Wednesday evenings, but I dunno if that's still going ahead or not. They usually have a plethora of hi-po cars there ranging from sleeper-spec commodores to oldskool muscle (Monaros, Chargers, yank iron), to full-on dorifto style imports & old datsuns. I haven't been to one of those yet, usually because I drive past them on the way back from work (and just about rear end some kent at the lights because I'm looking the wrong way!), get home, see that there's two cars parked between the EB & the road, and give up
Oi next time you see me, gimme the horn or the finger or something that catches my attention

Bonus points for you if it's actually my gf driving the car & she comes back with stories of road rage
Also there's the good old Traralgon Maccas Friday night carpark shenanigans, but the cops clamped down on that a while back, so I dunno if it's still on. You used to get all sorts there: ricers, ferals (utes/fourbys + rum stickers & kentry music), the commodore brigade, and the odd ford. I went a couple of times, but the VZ/BAs in steelies with extra aerials parked near Kmart Tyre & Auto kinda put me off.
I think there's a hotrod show in Maffra this weekend, but fark that, it's Maffra
