You probably don't want to hear what I pay, mine is a segregated policy and very cheap based on the group it insures. My 'Vette runs about $750 a year and that includes 12 month coverage, I intend to suspend collision in the winter so that will get cheaper. It does include a mandatory $1k deductible which according to my company is not negotiable for the C7.
I should mention it is not a daily driver, less than 10k a year, recreational use only. Sits in a garage , store it in the winter. Have full replacement value as well but I think it goes out only 3 yrs.
