If you are an old fart, try AARP / Harford. I added my ERA to my policy with no problemmo. After nearly 20 years with that lizard company, I changed to AARP and my premium dropped nearly 45% per year.
I insure my new Ford Sport Trac (AKA the official Cobra tow vehicle), my Isuzu Vehi-Cross (amazingly cool, collectible SUV) and the Cobra for just under $1,800 gazoutas per year. They also say they will add my Lotus Turbo Esprit with no problems (currently undergoing a makeover
)
