I think both Hagerty and Grundy are good choices. Hagerty is typically a bit less. You can get an instant online quote with each company to compare. Neither company requires an appraisal. Just tell them how much insurance you want, send 2 pictures, fill out the application and pay the first year's premium and that's it. In the case of a total loss, they will pay the value of your policy. try
