Alternative option

[David Hodgson]

It's not a G-Force, it looks to be an old Auto Styling. These were also out of WA but very basic chassis mods compared to the G-Force options. If you are not in WA, it may be difficult (not impossible - read $$$) to have the chassis approved elsewhere. Also if the chassis is not shortened in the correct location, you won't be able to get the seats in low enough and you will be sitting with your head above the windscreen height.
If you can get more pics I can probably tell you some more about it. Is it close to you?

Not sure if straight gas is an option for NSW rego any more so the engine may not be of use to you. This was certainly an option in NSW as recent as 6 or 7 years back. You should check all this before any decision and before continuing your search.

If you are purely after a cruiser then it could be worth your while, but if you want it to perform reasonable on a track day, understand there will most likely be more work than fully fabricated chassis kits. Brakes and steering will need upgrades, diff upgrade if using anything more than a sedate 302 driven by Nanna. This is not to say they won't perform. There was one at the Nats running in the low 1:13's and placed 35th out of 61, but he was suffering brake issues by 3rd lap.

What you win on purchase price will be lost on parts and labour.

I have a G-Force Crown chassis with Jag rear, and are planning brake and steering upgrades. I like my Cobra because I'm attached to it and it suited my circumstance at the time, but if I were to build again, it would NOT be another Crown chassis one.
