I use American Collectors and have for years and YES I have had a claim...  handled without a single problem or even a question completely to my satisfaction...

BUT the price seems high to me... even though the car is NOT quite
25 years old...(That is the age when the price falls drastically)...

I insure 5 Corvettes and a 68 Chevelle with slightly inflated values for just under 800 a year with American Collectors 

BUT ... your zip code as a HELL OF A LOT TO DO WITH YOUR RATES...

My Brother paid much more to Insure his Corvette then I did  and he only lived 70 miles away from me in the same State....

BTW...American collectors does offer multiple car discounts...
I just pulled out my policy
       Bodily injusry rate for my 1st insured Corvette (72) is $22.00
       Rate on car Number 2 (a 76)        drops to   $11.00
       Rate on car Number 3 (79)           drops to   $10.00
       Rate on the 64.. & 95 and the Chevelle is       IS ZERO
       
  Same drop in rates for the Person Protection. Uninsured  Motorist
   for each car also...

Nice thing is that Towing is only charged for the 1st car...all the
other cars  have towing INCLUDED at no charge.... 
 
 It did take a little "talking" on my part for them to Insure my 95 since it is so "new" lol  but they did....  Good customers even those with a claim get some breaks ...
