I just switched from State Farm to Nationwide and State Farm was reasonable, though I wasn't necessarily happy with the coverage. It was only $79 a month for full coverage, but they didn't have accident forgiveness, if I got into an accident, I would have to pay 20% of the rental fee for a car, and the lowest deductible for collision they will go is $250. I switched to Nationwide a week ago and the quote was for $70 a month, (every little bit counts) but the big difference is the coverage. I got accident forgiveness included, also they pay 100% of car rental fee, and I only have $100 deductible for collision. However they do have $0 deductible but 100 I can do. This is for a 2011 Ford Focus which Focuses are generally cheap to insure.
All classic car insurers share a few vital elements. Primarily, they all have an "agreed value" stipulation which allows you to set how much you think your vehicle is worth in the event of a total loss. They also all provide pivotal comprehensive and collision insurance to protect your vehicle from anything that may damage it. There does exist however, several key differences. While the field of companies for classic cars is not as vast as it is for normal cars, some classic car insurers are better than others.
