Funny you say that about Grundy and Allstate.
I called Grundy and talked to them about what year Viper I wanted to insure. Ended up being $624 per year with $0 deductible, and tow reimbursement up to $250 per tow. Also, when I asked them what the mileage limit was, I was told there is none. Just don't turn it into the daily driver. LOL
As for Allstate, we also pay more for insuring the two other cars..............hell, we pay more for 1 car per every 6 months then at Grundy!
BTW: Called Barret-Jackson directly and it was $746 annually, and Hagerty was $916 annually.
