I'm insured by Grundy as the agent and the policy is written by Chubb Group. I don't think there is much difference in premium between a BB and a SB. I insure my '66 for $65,000 and my '60 for $50,000, both agreed value. The '66 is a 427/390 and the '60 is a 283/230. I carry $500,000 liability insurance on both because an umbrella policy I have requires that as a minimum. The '66 costs me $402.50 a year. The '60 costs me $345.00 a year. The $57.50 difference probably has to do with the difference in agreed value rather than the difference in cubic inches. Me? I'd charge more for the '60 with it's drum brakes! :W I dropped Great American previously because they would only insure my '66 for $48,000 and wanted $367/yr for that. By the way. The coverage on the '60 went down to $345 from $360 upon renewal this year with Grundy.
I do not recall if Grundy asked me about modifications but I'd give those folks a call. They were very easy to deal with. American made me jump through hoops to buy insurance. They even required signed statements from my two sons evidencing their understanding that they were not covered if they drove the car! Since one of them was away at college that was a real hassle. I talked to Grundy's reps at Carlisle and decided to make the switch. Give them a call and tell them what you've got. They can probably give you a quote over the phone. :blue:
