Hi,
I'm in the Insurance industry and i have found Shannon's to have the best reputation , they seem to understand Unique Vehicles and their use. The old story , especially in Insurance , if the price is too good to be true , it probably is !!
Always check what the excess structure is , and make sure you Disclose any skeletons or driving history you have , Insurance companies can decline a claim if you have not disclosed your convictions , either vehicle or "Other" ??
I have my toy with Shannons , approx $350.00 for 12k Agreed Value in West Aust , but the work vehicles are all self insured..
