Collector Car Insurance

They call in "inflation guard" protection with an annual increase of 4% each year. Wasn't aware of it when I first signed-on.

Little hard to find a definition but from one of their pages:

The Inflation Guard on Standard Collector Car Policies

Grundy collector car policies have a built in Inflation Guard, which in recent years has automatically increased the insured value of your vehicle(s) by 4%. This increase is shown on your policy at each renewal and is reflected in a small premium increase for the added coverage. (N.Y., Mass. and S.C. policies do not currently include the Inflation Guard.)

Although the Inflation Guard works adequately to cover the increased cost of repair and market appreciation on most cars, extremely rare and valuable cars are often appreciating much faster than other collectors in the market place. For this reason, many of Grundy's large collectors are provided a "Collections Policy" which provides "peace of mind" and up to 150% of the value at which their car is insured.

I could certainly be wrong but I wouldn't be too surprised if most specialty policies didn't increase some from year to year - like health insurance. :(
