I have Hagerty at $20K on my truck, and it's about $250-300/yr. It's not just errands, but you can't drive to work either. If I recall correctly, a policy like Hagerty or Grundy is a TRUE full value replacement for amount insured, no questions asked whereas "stated value" policies don't necessarily pay out your stated value (they will depreciate and comp your truck like a normal policy, even if you have a stated value on record).
There are some good threads here somewhere on this from those with experience filing claims. I just know that Hagerty pays with little or no hassle. Lose your truck, get a check. BUT, if I can get a better premium with less restrictions than I'm all ears.
I'm going to check out the company that Big_Al_71 mentioned. That's a smoking deal especially for Miami! We used to live there and we moved from Miami-Dade to Broward in the same month I turned 25. My regular car insurance was cut by around 30%. A couple years later we left the state and it was cut again by 30%. AHHH, the fun of South Florida.
EDIT: Aha, found the link I was thinking of right under my nose in FAQ. Thank you Zonaman:
