Kamal,
Welcome to the forum mate. Yes the Cobra looks good there.
Perhaps the 'CH' plate option could be the go..?
There are a number of GT40's and similiar cars running around on these plates.
I think the Cobra Club is looking into that option. Perhaps the next Cobra event in Melbourne would be worth your attending. Grab a 7 day permit perhaps to attend in your Cobra...
Again, welcome to the Forum
