Its hard to know what is happening to prices of "Aussie Muscle Cars"
With these 2 HK 327s, the Warwick Yellow car was a better car ( not as good as some would have you believe) But not worth 100K more

There are better HK 327s around than both these cars..
With the colours, Warwick Yellow & Silver Mink are the most sort after and would command a slightly higher price, still not 100K more.
The Warwick Yellow 327 was sold to a phone bidder from WA unseen, and in my opinon paid too much, sure it was one of the "Hero Colours"
The other thing that happens is you get 2 cashed up buyers and it sends the Price higher than you would think, then when you run out of cashed up buyers the prices don't reach those same $$$.
Also there is people out there in the big world whose aim is push prices as high as they can purely for a Quick Profit.
These people are not genuine Enthusiats of "Aussie Muscle Cars"
If one of the Best HK 327 Monaros came on the Market, this woud create a lot of interest with the genuine Enthusiats and high $$$ would most likely happen.
Some sellers are trying to sell second rate cars or worse for big $$$
Buyer Beware
Its also happening with Fraud GTs etc
My two bobs worth
