Seems like this question comes up every other week. Sounds like Grundy.com has been mentioned a lot. They have an online quote where you can feed in the info and it will give you the rate. They have set agreed values on the car, which is what the premiums are based on that you will be purchasing. Now this policy here ONLY works as your Vette being a pleasure car and NOT an everyday driver. The policy is only for a car that’s to be used as pleasure use, on weekend trips, shows or something like a Sunday drive and not back and forth to work. Here is a link you may want to check out:
