Gott & Wyne would not cover my Morgan's as they were 'beyond our threshold'; whatever that means! The cheapest cover that I got was through Mogsure (Boncaster), I was previously with Headley.
It's a classic policy for Morgan's and as such you do not need a no-claim bonus as they quote you nett. Limited mileage 7,500 miles p.a., track days, etc, etc.
