Hagerty used to have a list of modifications that they would not accept. It was on their website. Cage, blower, nitrous, etc. It is no longer listed there. Even when it was, people claimed (and I believe them) that they would call Hagerty and ask about mods, and get the "Oh, sure, it's fine" line from whomever they spoke with, even when the website clearly said otherwise. This is why calling to ask, and then verifying in writing by reading the policy, is the only way to know for sure.



It was not stated value. It was agreed value. Big difference. Hagerty doesn't sell stated amount/stated value policies.
