I had Haggerty for a few years. After adding the Vette last year the premium was just over $850 for the bird insured for 25k and the vette insured for 18k. Seemed kind of high to me so I called Grundy. Same exact coverage for around $500 for both. I had to change although I will say that Haggerty is easier to deal with. Very nice people there.
Grundy says something like you can't drive to work regularly. I have vintage plates on both cars so according to the state of Michigan I am not supposed to use them for "regular" driving.
