Might be an idea? even bring a few decent 'lines and classic nissans mebbe?
Last friday of every month there is a car show at the Big Fish/Humble Pie. (Used to be an old go-kart track there that you could see from the highway, and a driving range, 9 holes....)
Its about 30min north of bris, 40min south of sunny coast, just on the highway out from caboolture. Good midpoint.
Place normally kicks off about 6.30-7pm and carries into the night. Always a good turnout of old classic muscle, V8s and a STUPID amount of sh!tbox commos but always some high end cars there.
Happens every month so no urgency, just an EOI. I'll be taking my 85 ford... muscle haha.
