you are covered for track events with shannons, YOU must notify them first before going for track events.. in saying that it must be a club orientated track event.. ie the car club u belong to.
reason shannons ask you those questions is to see if your worth the risk to insure plus if you match there minimum requirements under their business scheme.
end of the day... doesnt matter who you insure with.. aami, just cars, shannons, gio, custom cars ...there all owned under the same company.. what your paying for is the service provided.
basically just weigh out the pros and cons and see which is suited to you.
