Antique auto insurance recommendations?

I have used my State Farm insurance company for over 12 years. They have a special classic vehicle rate program but it also comes with some limitations such as how many miles you can drive per year, how often, etc. VERY CHEAP RATES. I do NOT have a garage either. I had a Corvair Convertable last year and asked for $4000.00 coverage as a "daily driver". That means no restrictions or limits on how often or where I could drive. They refused my request but offered $8000.00 instead at the same rate. Car got totaled a few months later and they paid off the $8000.00. In fact, they even re-imbursed me for my tag and taxes I had paid. Never had that before ever.
