Above post references daily driver, you will need to be able to tell them you have a daily driver with a current policy on it.
Hagerty is really easy to work with, I would also suggest being careful how you answer some of their questions. Sometimes they will be somewhat misleading, for example, if it's built at all for performance, I tell them yes, but the engine is a original Mopar piece etc.
They don't mind mods but there are some things that will limit what you can do.
I also don't volunteer any info, I answer their questions as carefully and as closely as I can.
What are some of the details of your ride?
