No such company in Canada.
Hagerty I world wide I think!

Hagerty never questions when I raise the the value of my four cars I have insured with them. I justify it ("new motor", "paintwork", etc.) and tell them how much to increase the value. Bam!, Done. Piece of cake.
FYI: They cared more about the security at the storage unit where I sometimes garage the car.

I use Grundy. They raise it automatically every year.

Your premium or agreed value?
 

I have Haggerty - I don't know if I have the "Value Analysis" on my policy - they seem to automatically raise the value a few percent per year. It looks like my Mustang is valued far above market price, and I could probably save a small amount per year by reducing the agreed value - but I just leave it alone. I had no problem last year when my Mustang was damaged by falling objects in my garage. ( my own fault for overloading my parts shelf). Haggerty did not change my premium, and the classic car repair place that they recommended to do the work did an amazing repair job. The car is definitely better now than before the damage.
