Hi Dave,
Very nice car mate. I would get Shannons to Insure it for at least $50K mate as you have to remember that if it is written off how long and hard it will be to to get another one and more then likely cost more then you paid for this one. You will also find some other things to spend money on when you get it.
I have mine Insured for 60K with Shannons and it cost $588.00 and that is the only policy I have with them.
Just an idea for you to consider. These cars are worth more in Aus then US at the moment so Inusre it for the replacement value here.
Cheers
