Probably...it's a Super C. Some insurance co's don't understand, they just rate on your VIN and value. Next, most rates are for replacement cost if it is less than 5 or 7 yrs. old. Many other variables as to Why?
What really T'ed me was getting quotes before purchase, then calling the same co.'s after purchase and they tell me "Oh, we can't insure that." Can't drive our new to us coach off the lot.
Kinda like our home insurance....the market value is $120K, but to insure it (rebuild it) the value is $287K. Which value you think they rate on? Which value do you think the next owner would pay?
