its not only your age...it also is theft rates, not only by car, but by city u live in...
i pay about the same as you, a year full coverage w/full glass...on my 04 impala
Do you have a contact or site link for Hagerty? Is it a nation wide company? I've kept the hardbody on GL for now cause it's not being driven but to the shop and back to storage. I've been wanting to look into some show vehicle coverage.
i just turned 30 last week and i now pay $836 every 6 months ($1672 a year) for full coverage on 2 vehicles thru Allstate
