I have written before about insuring a classic car. It is different than insuring any other type of car because your car will INCREASE in value, instead of depreciate.
The NY Times has a story about Hagerty Insurance. They may be the largest insurance company for classic cars. I read their website and some other sources about the company. If you own a classic car, you owe it to yourself to check them out. (And I don’t endorse too many insurance companies!!)
