Just a hypothetical query to put to some of you who may work in insurance or own an Aston Martin but how much (ballpark figure) would it cost to insure an Aston Martin V12 Vanquish?

As you can imagine, most stupid insurance firms don't offer online quotes for such vehicles and won't provide a figure unless you ring them. I don't particularly want to waste their time with a (currently) hypothetical query.

Any of you guys able to shed any light on a rough figure?
