This topic is a common one over here while sinking a few cold ones...And here are my 2.5 cents worth...
I think the prices for Aussie classics will come down quite a bit in the future. Everything rises and falls. Sure they are going up and up now. But I think in 20-30 years it will be a whole different ball game. Lets play out a scenario of a kid born today, in February 2021.
Basically you want the cars that were Tough, looked cool cruising down your street or in town, basically what you drooled over when you were growing up. So a kid born today is not really going to know about Brock ruling the mountain in a torana, or the battles with Moffat except in history books. If he is a kid who is into cars, he will be into the cool cars cruising the streets when he is 15, which will be 2036. The car that he says to himself "I'm going to have one of those when I'm older.
In 2061, when the kid in question is 40 our beloved Torana's will be more than 80 years old. (So that is the equivalent of cars from the 40's to us today.) Now you are the the old codger that lives down the road from our 40 year old and you have a Torana in his shed, that you paid $100,000 for it way back in 2021, and you have decided to sell it to pay for your medical bills and up coming move to the old folks home. (Because you are well into your 80's now) Will that 40 year old in 2061 want to pay that sort of money for it?? I doubt it.
We love torana's, and if you're lucky enough to afford one and answer your childhood dream then good on you. But will the next generation want them???? If there is no desire for them in the coming decades then the prices will drop. My dad was a car nut and he raced in speedway, so we were raised around fast cars. But I know the cars that my dad thought were cool I wouldn't want to own and I think I even referred to them as shitters growing up as they were not cool cars to me.
So will that kid born today want to pay that much for a car that he has never even seen on the streets?? I doubt it. And this is one of these reasons that I think the value will drop out of classic aussie cars in the future. What will the kids born today, or even the 10 year olds desire?? More likely a vintage SS-V Commodore..............
