I WOULD NEVER INSURE MY VEHICLES WITH "Hagerty". They are just an agency, and they DO NOT UNDER WRITE the policy. Their underwriters have a horrible "bad faith " claims rating.
CHUBB under wrights their own policies and is the best in the industry. You get exactly what you pay for here. I would advise to pay a little more, insure the GT for $35K and sleep well. Just my .02 cents. Ask me how I know.
In addition with CHUBB you can drive to the store, to a movie, your friends house, etc. With Hagerty,...wait until you have a claim. You get what you pay for in this "game".
